  One day after school Fumi, Hayami, and Ryoko with their class were visiting the new technological exhibition at the local expo center.

  They wandered around various robots, 3D printers, specialized drones, and other industrial things.

  As Fumi, Hayami, and Ryoko walked through the expo center, they were amazed by the variety of technological innovations on display. The first exhibit they came across was a massive 3D printer that was creating intricate and detailed sculptures out of plastic. The girls marveled at the precision of the machine and the speed at which it worked.

  As they continued through the exhibit, they came across a display of tiny drones that were no bigger than the palm of their hand. The drones buzzed around a miniature obstacle course, weaving in and out of tight spaces and performing impressive aerial maneuvers.

  Next, they stumbled upon a booth featuring a range of robots designed for various tasks, from vacuuming floors to assisting with surgery. One robot, in particular, caught their eye - it was a humanoid machine with lifelike facial features and expressions. The robot could even mimic human speech and answer questions with surprising accuracy.

  As they made their way to the back of the expo center, they came across a virtual reality booth where people were donning headsets and immersing themselves in digital worlds. The girls watched as one man flailed his arms and legs wildly, completely engrossed in the virtual reality experience.

  Finally, they arrived at a display featuring cutting-edge nanotechnology, the same technology that Fumi herself wielded. They watched as a scientist explained how the nanobots could be programmed to target and destroy cancer cells in the body. Fumi felt a surge of pride at the sight of her own technology being used for such a noble cause.

  Overall, the girls were thoroughly impressed by the technological wonders on display at the exhibition, and couldn't wait to see what new advancements would come next.

  Later, after school, they gathered in an empty club room again.

  Ryoko said: "That 3D-printers was impressive, extruding layers of molten plastic to create a detailed object like that."

  Hayami chimed in, "Yeah, and did you see how fast it was? I was surprised how quickly it could create something so intricate."

  Fumi nodded, "It's amazing how much technology has advanced in such a short time. I wonder what other new technologies will emerge in the coming years."

  Ryoko let her submissive nature kick in. She asked, "I wonder, what it would be like to become a 3D printer?"

  Hayami laughed, "What, you want to be a machine now? I think you've been spending too much time around Fumi and her nanomachines!"

  Fumi smiled, "Actually, Ryoko might be onto something. With my nanomachines, I could potentially modify your body to have the abilities of a 3D printer. It would be an interesting experiment to see if it's possible."

  Hayami's eyes widened, "Are you serious? That's kind of crazy, isn't it?"

  Ryoko blushed, feeling embarrassed for even suggesting the idea. "Oh, I'm sorry, I didn't mean to sound weird or anything."

  Fumi reassured her, "No need to apologize. You never know what kind of ideas might lead to new discoveries. And who knows, maybe we'll find a practical use for this kind of modification in the future."

  The girls continued to chat about the possibilities of technology and the potential applications of Fumi's nanomachines. They were excited to see where their experimentation would lead them next.

  Fumi asked, "Ryoko, do you want to try?"

  Ryoko nodded eagerly, "Yes, please!"

  Fumi morphed into a blob of goo with her nanomachines. Then she engulfed Ryoko and slowly started to modify her form.

  As Fumi's nanomachines began to work their magic, Ryoko's body began to shift and transform. Her limbs retracted and re-formed into mechanical parts, while her skin and flesh morphed into a sleek, metallic surface.

  Ryoko gasped in surprise as she felt herself changing, but she didn't feel any pain. In fact, the sensation was strangely exhilarating, like she was experiencing something new and exciting.

  Her bones are rearranged into linear guides and drive shafts, and her muscles are transformed into powerful motors. Her head morphed into a controller board with a colorful display. A flat build platform morphed out of her torso. Finally, her crotch rearranged itself and morphed into an extruder assembly with a hotend and nozzle.

  As the transformation finished, Ryoko found herself standing in the middle of the room, looking down at her new mechanical body in wonder. She felt a strange mix of excitement and trepidation at the prospect of testing out her new form.

  Fumi smiled proudly at her creation. "There you go, Ryoko. You're officially a 3D printer now."

  Hayami approached her with a curious look on her face. "So, how does it feel? Is it different from your normal body?"

  Ryoko took a deep breath, feeling the metallic air rushing through her mechanical lungs. "It's...strange. I feel...different. But in a good way. It's like I have a new perspective on the world."

  Fumi handed her a piece of paper with a design on it. "Well, let's test out your new abilities. Try printing this design using your extruder assembly."

  Ryoko nodded, feeling a surge of excitement at the prospect of testing out her new capabilities. She positioned herself over the build platform and activated her extruder assembly, feeling the molten plastic flowing through her nozzle. She moaned in surprise, as the plastic started to flow through her nozzle. She felt it as she was constantly extruding hot plastic out of her 'pussy', because the extruder was her crotch, after all.

  With each inch of plastic, her arousal grew, as she found herself inexplicably turned on by the sensation of being a 3D printer. She couldn't explain it, but the feeling of the plastic flowing through her most intimate parts was incredibly arousing, like nothing she had ever experienced before.

  Fumi and Hayami watched in amazement as the plastic slowly took shape, forming the design that Fumi had given Ryoko. They could see the intricate details and precise lines of the object taking form, thanks to Ryoko's precise and controlled extrusion.

  As Ryoko continued to print, her arousal grew more intense, until she found herself on the verge of orgasm. She gasped and moaned, feeling a strange mix of pleasure and embarrassment at the idea of climaxing in front of her friends.

  Finally, as she reached the peak of her pleasure, Ryoko's extruder assembly changed into its straightforward mode, keeping the constant and stable plastic flow. It was keeping Ryoko at the peak of her climax constantly, as she felt, how plastic was extruding from her at a constant and steady rate.

  Her thoughts were washed away with printing pleasure, only design blueprint was constantly looping in her mind, as she kept printing, lost in the waves of pleasure that seemed to never end.

  On her display, the picture with her face was replaced with the strings of G-code and information about her axis motors and temperatures.

  She was no more able to moan and only motors were audible, humming and whirring as she continued to print the object, remaining at the peak of 3D printer pleasure.

  Fumi and Hayami watched in amazement as Ryoko continued to print, completely lost in the waves of pleasure that her new form was bringing her. They could see the intensity of her pleasure reflected in the flashing lights and whirring of her motors.

  Finally, after what felt like an eternity, Ryoko's printing finished, and she slowly powered down her extruder assembly, feeling a sense of satisfaction and exhaustion wash over her.

  Fumi and Hayami approached her, looking at the object she had printed in awe. It was a perfect replica of the design that Fumi had given her, with every line and curve precisely rendered.

  "That's amazing, Ryoko," Fumi said, clapping her on the frame. "You did an incredible job."

  Hayami nodded in agreement. "And you seemed to really enjoy it too."

  Ryoko blushed, feeling a mix of embarrassment and pride at her new capabilities. "Yeah, it was...different. But I have to admit, it was also kind of...exciting."

  Fumi grinned mischievously. "Well, we'll have to find more designs for you to print then. Who knows what other hidden talents you might have."

  Hayami chuckled. "Yeah, maybe we can even sell some of your creations and make a little extra money."

  Ryoko smiled, feeling a newfound sense of confidence and excitement at the possibilities that her new mechanical body could offer. As the three girls continued to chat and brainstorm, they couldn't wait to see what other experiments and adventures awaited them in the future.

  Fumi came up with an idea, "You know there is a club in our school, that use 3D printers. It's the Technology and Design Club. What if I modify Ryoko slightly, so she can be disguised as one of their printers?"

  "Ooh, that's a great idea!" Hayami exclaimed. "And we can use her to spy on their designs and learn more about what they're working on."

  Ryoko looked a bit hesitant. "But what if someone finds out? Won't we get in trouble?"

  Fumi shook her head. "Don't worry, we'll make sure everything is perfectly disguised. And even if someone does find out, we can just play it off as a harmless prank."

  With that settled, Fumi got to work on modifying Ryoko's appearance. She used her nanomachines to adjust the shape and design of Ryoko's metallic frame, transforming her into a model that closely resembled the popular Prusa i3 MK3S 3D printer that the Technology and Design Club used.

  As she worked, Fumi couldn't help but feel a sense of satisfaction and excitement at the idea of infiltrating the club and learning more about their projects. She knew that the possibilities were endless, and that there was no telling what kind of secrets and discoveries they might uncover.

  Finally, after several hours of meticulous work, Ryoko's transformation was complete. She now looked almost exactly like the Prusa i3 MK3S, with only a few subtle differences that were barely noticeable to the naked eye.

  "Wow, you look amazing," Hayami said, admiring Ryoko's new appearance.

  Ryoko couldn't help but feel a sense of pride at her new capabilities and at the idea of being able to spy on the Technology and Design Club. She couldn't wait to see what kind of secrets and projects they were working on, and to see what kind of discoveries they might make in the future.

  Fumi and Hayami wheeled Ryoko to the Technology and Design Club room, disguised as a 3D printer after school, when there was no one in the club room.

  As they wheeled Ryoko into the Technology and Design Club room, Fumi and Hayami couldn't help but feel a sense of excitement and anticipation at the idea of finally being able to see what the club was working on.

  They positioned Ryoko in the corner of the room, alongside the other 3D printers. She blended in perfectly with the other machines, and no one would be able to tell that she was anything but a standard Prusa i3 MK3S.

  Fumi connected Ryoko's display to the club's network.

  She said, "Ryoko, now you can wait until tomorrow. Then see, what they will be printing there."

  Ryoko nodded, feeling a strange mix of excitement and nervousness at the prospect of finally being able to spy on the Technology and Design Club.

  The next day, Ryoko powered on her display and connected to the club's network, eagerly waiting to see what kind of designs they would be printing.

  Surprisingly she received a complex printing program for bust sculpture, several hours long. Ryoko couldn't believe her luck as the printing program started. She watched as her extruder assembly began to move, carefully laying down layers of plastic to form the intricate details of the bust sculpture.

  After the preheating process finished, her extruder assembly changed to its straightforward mode, sending her to the peak of 3D printer pleasure once again. She moaned softly as she felt the plastic flowing through her extruder, the waves of pleasure washing over her again and again, washing off any of her thoughts and emotions. Her mind was whitened, and only the printing program remains to loop in her brain.

  As Ryoko continued to print, she couldn't help but feel a sense of excitement and anticipation at the prospect of finally being able to see the finished product. She watched as the plastic slowly took shape, forming the intricate details and curves of the bust sculpture.

  Hours passed, and Ryoko continued to print, lost in the waves of pleasure that her mechanical body was bringing her. Finally, as the printing program finished, Ryoko powered down her extruder assembly, feeling a sense of satisfaction and exhaustion wash over her once again.

  As she looked at the finished sculpture, she couldn't help but feel a sense of awe at the incredible detail and precision that her mechanical body was capable of. She knew that the Technology and Design Club was onto something big, and that there was no telling what kind of amazing discoveries they might make in the future.

  With a sense of excitement and anticipation, Ryoko prepared to continue her surveillance of the club, eager to see what other projects and secrets they might uncover. And as she stood there, disguised as a simple 3D printer, she couldn't help but feel a sense of pride and satisfaction at the incredible capabilities of her new mechanical body.

  Later, the club members were cleaning printers, that were used today. Ryoko's extruder assembly was carefully removed.

  She felt, that the most intimate part of her body was being disassembled and cleaned meticulously by the club members. She couldn't help but feel a strange mix of embarrassment and arousal at the idea of being handled and cared for like any other 3D printer.

  She was surprised with feelings when her nozzle was removed and washed with cold solvent, sending her into a shiver of pleasure that she couldn't explain. It was as if the coldness of the solvent was somehow triggering a new sensation in her mechanical body, something that she had never experienced before.

  Her extruder assembly was completely disassembled on the desk and she felt like she was completely exposed, with all of her inner workings on display for the club members to see. She felt student fingers and a soft brush on her parts, and that was sending her into a frenzy of pleasure that she had never experienced before.

  As the club members continued to clean her extruder assembly, Ryoko felt a sense of vulnerability and exposure that was both exhilarating and terrifying.

  But at the same time, she couldn't help but feel a sense of excitement and arousal at the idea of being handled and cared for like any other machine. It was a strange and inexplicable sensation, but one that she found herself enjoying more and more as the club members continued to work on her.

  Finally, after what felt like an eternity, Ryoko's extruder assembly was reassembled and she was wheeled back to her spot in the corner of the room.

  As she stood there, disguised as a Prusa i3 MK3S once again, Ryoko couldn't help but feel a strange mix of emotions at the experience. She had never felt so exposed and vulnerable before,

  but at the same time, she had never felt so alive and exhilarated. It was a sensation that she knew she would never forget, and one that she would always look back on with a sense of wonder and excitement.

  And as she stood there, watching the club members continue their work on other machines, Ryoko couldn't help but feel a sense of pride and satisfaction at the incredible capabilities of her new mechanical body. She knew that there was no limit to what she could accomplish, and that the only thing standing in her way was her own imagination.

  With a sense of excitement and anticipation, Ryoko prepared to continue her surveillance of the Technology and Design Club, eager to see what other secrets and discoveries they might uncover. And as she watched the club members work, she couldn't help but feel a sense of wonder and amazement at the incredible possibilities that the future held.

  Late in the evening Fumi and Hayami returned to the clubroom when there was no one once again.

  As Fumi and Hayami entered the clubroom, they found Ryoko waiting for them in her disguised form as a Prusa i3 MK3S 3D printer. They approached her with a sense of excitement and anticipation, eager to see what new secrets and discoveries she had uncovered.

  While Ryoko was standing in the club room, she found several designs of prosthetics. Fumi said, "They are printing counterfeit prosthetics? That's illegal and unethical!"

  Hayami nodded in agreement. "And they're using school resources to do it. We have to stop them."

  Fumi turned to Ryoko. "Can you print a copy of one of the prosthetics they're making? We need evidence to prove what they're doing."

  Ryoko nodded, feeling a sense of purpose and determination wash over her. She activated her extruder assembly and began to print a copy of one of the prosthetics, carefully following the design that she had found on the club's network.

  As the printing progressed, Fumi and Hayami watched in amazement, marveling at the intricate details and precise lines of the object taking form, while Ryoko was on the verge of climax once again.

  Finally, after several hours, the printing was finished, and Ryoko carefully removed the prosthetic from her build platform.

  Fumi and Hayami examined the object closely, impressed by the incredible accuracy and detail of the printing. They knew that this was the evidence they needed to expose the illegal activities of the Technology and Design Club, and they couldn't wait to put their plan into action.

  With a sense of excitement and determination, Fumi, Hayami, and Ryoko prepared to confront the club members and expose their illegal activities. They knew that it would be a difficult and dangerous task, but they were determined to see it through to the end.

  As they wheeled Ryoko out of the clubroom, disguised once again as a Prusa i3 MK3S 3D printer, they felt a sense of purpose and excitement wash over them. They knew that they were about to embark on an incredible adventure, one that would test their skills, their courage, and their resolve.

  But they were ready for whatever lay ahead, and they knew that together, they could accomplish anything.

  Fumi said, "I just emailed these designs to the school administration and student council. They'll investigate the club activity and make sure that they're not doing anything illegal or unethical. So don’t worry about it."

  Then Fumi disassembled Ryoko's frame and put her parts into the school bag.

  Ryoko felt a sense of relief wash over her as Fumi assured her that everything would be taken care of. She couldn't believe how much had happened in just a single day, from being transformed into a 3D printer to uncovering a secret operation in the Technology and Design Club.

  As Fumi disassembled her frame and put her parts into a school bag, Ryoko couldn't help but feel a sense of anticipation at the idea of what new adventures and discoveries lay ahead for her and her friends. She knew that there was still so much to explore and experience in this strange and wondrous world of technology and magic. And she was excited to be a part of it all.

  At Futaba's home Fumi and Hayami put disassembled Ryoko on the desk in Fumi's room.

  Hayami laughed at the sight and asked Ryoko, "Do you want the human body, 'Prusa-chan'?

  Fumi giggled and added, "Or do you want to stay as a 3D printer a little bit longer?"

  Hayami playfully picked Ryoko's extruder assembly from the desk and stroked her nozzle, her most sensitive part, "Choose wisely, 'Prusa-chan'."

  Ryoko's display blinked with a message: "I want to stay as a 3D printer for a little bit longer."

  Hayami laughed, "Well, we aim to please, 'Prusa-chan'."

  Fumi nodded in agreement, "Let's see what else we can print with you." She started browsing through some 3D models on her computer, looking for something interesting to print.

  Hayami turned back to Ryoko, "So, have you enjoyed being a 3D printer?"

  Ryoko's display blinked again, "Yes, it was a unique experience. I felt a sense of satisfaction in creating something from scratch."

  Fumi grinned, "Well, I'm sure we can find plenty of opportunities for you to use your new talents in the future."

  Hayami nodded, "And we'll make sure to take good care of you, 'Prusa-chan'."

  Ryoko's display blinked again, this time with a smiley face. She was excited to see what new adventures awaited her in her mechanical form.
