Bowden Extruder Experimental

Experimental new bowden extruder.
Fits well within the very limited space of the Overlord 3D printer.

Uses the MK8 driving gear with very sharp fine teeth.
( See this page for reference, can probably be found cheaper: http://www.3dprima.com/sv/tillbehor/reservdelar/wanhao/wanhao-mk89-drive-gear.html )

You will need to use a M8 tap to tap the holes for the bowden pushfittings.
