Printrbot Simple Direct Drive Bowden conversion by dby

Last crawled date: 3 years ago

Improved version at http://www.thingiverse.com/thing:305215
Parts to convert a PrintrBot Simple with a direct drive extruder (not aluminium) to make use of a Bowden tube. No changes to the Simple itself are required (no new holes etc.).
Motor and extruder are mounted on the Z axis support bars.
All parts are sized to be printable with a Simple.
UPDATE v2:
Redesign of extruder and extruder model support so that the extruder unit can rotate as required to alleviate pressure on the bowden tube as it bends. This has allowed the tube to be less than a foot long.
Extruder fitting is an adaptation of the Internal filament guide for Printrbot direct drive extruder by rswarner.
The Hotend fitting is an adaptation of one of the fittings in Printrbot Simple Bowden conversion by owens to make it fit the new extruder location.
