Hey! This thing is still a Work in Progress.
Files, instructions, and other stuff might change!

Description
Or was that a perimetric parastaltic pump ?
This is a peristaltic pump built in openscad.
There have been a number of peristaltic pumps recently and I thought a parametric one would be cool.

The motor mounting still needs some work but its a start

Instructions
Alter the pipe_od and pipe_wall variables for the pipe that you have.
Alter the bolt_size and bolt_length for some bolts you have in your shed
If you wish to use bearings alter the wheel_radius and wheel_thickness for the bearings that you want.
Check the assembly in mode 2 ( exploded for overlaps etc )

What these pumps (all the ones on thingiverse) need:
Multiple pump bodies on the same shaft (to even out the peristalsis)
Planetary or other extreme gear reduction (most small motors don't have enough torque to drive one of these)
