Yet another peristaltic pump
thingiverse
I'm working together with a geared Nema17 stepper motor that has an 8mm flanged output shaft, just like this one: http://2.wlimg.com/product_images/bc-full/dir_37/1091420/geared-stepper-motor-1392929.jpg. I am using 10mm OD surgical tubing to get the job done. You can check out an action video here: https://www.youtube.com/watch?v=2H4FfgKZpxs. The bearings are of type 688 and are fixed in place with M8x12mm screws, available at https://www.vxb.com/MR688-2RS-Double-Bore-Dia-8mm-OD-16mm-Width-5mm-p/mr688-2rs.htm.
