We'd love to hear from you if the print was successful.

It uses SeeMeCNC's drive gear, but any 12mm OD drive gear should work if you line it up properly. The spring from the EZStruder is meant to be used for the arm. The bearing that attaches to the arm is a 608 and it gets fastened by an M4 bolt and washer combo. It is designed to use a PTC connector that E3d provides that allows the PTFE tube to go right up to the drive gear
This is R7.7, the original design release was R3. I have made changes that should improve the ability to use TPU type filaments (Ninjaflex, Filaflex, etc) after testing indicated this was an issue.
The Arm file is inverted. When you export it to an STL you will need to flip it.
