Mini Peristaltic Pump

I designed a miniature peristaltic pump using a 6v N20 geared motor. Tubing is 4mm OD and 2mm ID. Rollers are made from Mcmaster-Carr part#8627K129 2 Screws are part#99461A615 2 Small screws are part#91305A002 Housing can be resin printed (hard resin) or machined. I used a Pocket NC V2, 5 axis desktop machine and machined from a 1 inch bar stock. Spin plate machined for press fit onto motor shaft. Top cover was 3D printed of PETG.
