A peristaltic pump i designed in Fusion 360 to learn about modeling mechanisms. I designed it to work with a geared stepper motor that i took off of a commercially available peristaltic pump, but since not everyone has access to these motors i am currently working on a version of 'bottommk2' and 'mainmk2' that will fit a NEMA17 motor.

Print in ABS or PETG for best results. Needs 3mm screws to hold everything together, and a 5mm silicone hose tube.

For those curious, a peristaltic pump is a pump that pumps fluid through a hose without the liquid making contact with any mechanical parts. It's used in the medical industry to keep fluids sterile.
