Universal Paste Extruder for 3D printers

This is a universal paste extruder for RepRap and other 3D printers.

It allows you to experiment with various pastes on your 3D printer without the need for any air compressor equipment or valves etc.
It simply uses the existing Extruder motor output from your printer’s electronics.

It's designed to fit on the Quick-Fit X Carriage Thing 19590-

I challenge you to make one that works with 50ml Syringes! or do a fully parametric version in SCAD :)

And a very big thank you to Greg Frost (and derivatives) for the wonderful work done on the Parametric Involute Bevel and Spur Gears script, without this, the gear set would have taken me a lot more time to make.
