Peristaltic pump for NEMA 17 stepper motor https://youtu.be/LoKCXN6wbZM https://youtu.be/zMSOZYFtSEs Use base.stl if you want no mount and base_wallmount.stl to mount it somewhere. Use cable strips to fix the tubes on both ends. The pump can run in both directions. Requirements: - 22mm / 08mm bearing - 2.5 x 5 mm silicon tube - your favourite stepper driver - Arduino, ESP or similar Features: Depends on your code. For example: I use it with MQTT via WLAN to add algicide to my pool. Printing resolution is not mandatory. You should put a rubbery tape inside the frame where the tube is placed to take care of the tube.
