Printrbot Extruder Remix
thingiverse
I used TinkerCAD to mash up thing:281015 and thing:446480. I've also ran these through the netfabb cloud client to repair any mesh discrepancies. I've also added the pin from thing 281015 for completeness. Standard Arm Version:https://tinkercad.com/things/1zOgEpKKkNh Left Arm Version:https://tinkercad.com/things/cjlAE4hfMGQ Extruder Base:https://tinkercad.com/things/0KpDCJTWMsa Extruder Base Left:https://tinkercad.com/things/332oORRDXI1 Instructions Use the 'left' arm and base version if your extruder motor shaft is parallel to your x-axis, otherwise you should be fine with the standard version.
