Hybrid Wade's-Bowden Dual Extruder Mount for Printrbot

thingiverse

This model places a Bowden mount in front of the current Wade's extruder to work with my Printrbot Plus Dual Extruder project. I included a 1.75mm Bowden-driven extruder ahead of the initial 3mm Wade's extruder, but you need to add a bowden-to-hotend mount separately. I utilized a design from Thingiverse (http://www.thingiverse.com/thing:104005) for this. The X-carriage was adapted from noreway's Printrbot Plus Quick-Fit Upgrade (http://www.thingiverse.com/thing:96230). Ensuring both hotends are at the same height is crucial; I used washers to shim until I perfect this setup, after which I plan to combine the Bowden/Ubis mount into this frame. The OpenSCAD code needs refinement for wider use. For optimal strength, print with a .8 infill level.
