Customisable Peristaltic Pump

This is a powerful pump with a set of fast, sharp, moving cogs. Use it at your own risk and I assume you recognise that I accept no liability for what you do with this design.

The ready-made STL files are suitable for a 15mm OD, 12mm ID PVC hose (search for "12mm ID x 15mm OD - PVC Clear Hose Vinyl Tubing" - don't go for less than 5m), and can pump 6+ litres / minute with a head over 4 metres - the motor torque (once the cogs are released and greased) for pumping is good - easily managed by a consumer power drill, but will obviously be affected by the viscosity of what you are pushing through the pump. The print bed will need to accept about 220x220 mm with those files. One can easily make smaller pumps using the scad file - I have not tested that fully.

Here is a more recent video showing the pump shifting 12 litres of water from one bucket to another in 120 seconds: https://player.vimeo.com/video/864764282?badge=0&autopause=0&player_id=0&app_id=58479
