thingiverse
Simple 4-part peristaltic pump. Did a test, I was able to pumo 150ml/min Your can see it working here: https://youtu.be/ILWof-gsARc I designed it because I wanted to use the components I already had. Parts required: 2 11mmx5mmx4mm bearings (MR115ZZ) 10 M3x10mm bolts (Flat head) (I use just 4 bolts, that's the minimum) 4mm OD, 2mm ID silicone tubing, at least 12cm Assembly: Bolt the base to the motor Mount the bearings sandwiched between the arms (here you can bolt them if you want, I didn't as it really fits firmly on the motor shaft) Mount the constructed arm on the motor shaft, until the bearings almost touch the base Mount the body and bolt from below using the flaps.
