by RichRap, published
This is a Geared Peristaltic pump, designed for 3D printers to enable them to extrude various materials for building objects.
It's a work in progress, updates will follow, but the basic principle is up-and-running.
This Pump is designed to fit my Quick-Fit X Carriage - http://www.thingiverse.com/thing:19590

Take a look at my Blog for more details about the Pump and assembly.
The Tube is a critical part, it will either work or fail if you don't have the correct type and size of tube.
It needs a normal NEMA17 motor and 624 Bearings for the pressure pump element.
