I salvaged it from a pile of discarded computer parts. This design is based on the popular stepper motor, and my model follows this layout: https://www.thingiverse.com/thing:2848314 The silicon tube was obtained from an old inkjet printer, so its exact dimensions are unknown, but they're not crucial to the design. Feel free to adjust the roller dimensions to fit your specific silicon tube. All parts were printed in PLA and it functions as intended. I'm curious about its durability, particularly the rollers. If you can improve on this design, consider creating a more robust rotor with multiple arms and rollers. Check out the pump in action: https://youtu.be/G6Dr2ei7kmM
