GEARED BOWDEN EXTRUDER

UPDATE: I've remixed this design to mount on a 20/20 aluminium extrusion https://www.thingiverse.com/thing:2596124

UPDATE: So I have finally got around to sorting the support structure out for this design. It is much sturdier than the previous design and the fixing holes are in a better position.

UPDATE: I had the fixing post for the idler block randomly snap mid way through a print last night. Looking at the design this was a weak point. As a result I have made the fixing post wider. Hope
