About this 3D model
These are the parts you need to make a dual head extruder for your M2. The very base core design of the extruder drive, spool holder, and end stop, files come from MakerGear with heavy modifications. I would like to thank MG for making these files available on their GitHub. I had to completely redesign the motor mount and the print cooler is entirely original. Look on the instruction tab for more notes on this build. It is still a work in progress and suggestions are welcomed.
