MakerGear M2 Narrow Motor Mount for V4 extruder

thingiverse

I'm in the process of transforming my MakerGear M2 into a twin-extrusion setup as developed by Tim Edwards: http://opencircuitdesign.com/~tim/3d_printer/twin_project.html The factory-printed motor mount is wider than the motor itself, resulting in some lost travel on the X-axis. MakerGear now offers an all-metal motor mount that's really great, but relocates the wiring to the side and sacrifices even more X-travel (an issue exclusive to the twin-configuration). This new metal motor mount combines the best aspects of every other design I've seen. It uses the innovative wire organizer box from the metal motor mount, relocated to the top to avoid adding width to the extruder assembly beyond that of the motor itself. Files for this wiring box can be found here: https://github.com/MakerGear/M2/tree/master/Printed%20Parts/STL/V4%20Hotend It securely attaches to the front of the planetary gearbox like the metal mount, doing away with the clunky pinch-clamp assembly from the factory plastic design. The design is relatively compact and requires minimal plastic use. I manufacture it in ABS on a flat surface, backside up, at an infill rate of 60% or greater. The file's called "Metal Motor Mount" because I initially planned to machine it out of aluminum via CNC, but after 3D printing a prototype for test-fitting, the setup worked flawlessly and didn't require replacement with metal.
