Bounden extruder - direct drive by ceri Apr 25, 2013


A very simple and effective Direct Drive bowden extruder,
But using elastic bands instead of springs !

Photo is my V1, the lower screw just ouls finger grip,
but works just fine.

working very well so far.

This has been derived from my original extruder,
built from leftover pieces of plastic sheet !!

I printed at 0.5 mm
and 100 % fill.

Tapped the hole for Bearings to M5,
two * 626Z (6mm 19mm, 6mm)

and tubing to M4,

Also, cleaned up feed hole for lower arm.

Please use V2,
V1: the lower mount screw fouls finger grip :(
