PLEASE USE THE "ROTATED" PARTS OR ROTATE THEM YOURSELF IF YOU RECOMPILE/EXPORT IF NECESSARY I needed a peristaltic pump and wanted to use a motor from some old electronics. I geared it down with my motor gear reducer (thing:409598) and attached it to the output. The peripump itself definitely works (with a hand drill) but I'm currently assembling the gear reducer and will test it shortly.the pump uses 4 m4 bolts to hold the bearings in place, 1 longer ~40mm m4 bolt for the drive shaft, a few m4 nuts, and a few 20mm m3 bolts to hold it together (it secures nicely to my gear reducer).
