Stepper motor mount for the RigidBot. It has the following changes from the original RigidBot design:
1 - It is offset by 6mm to line up with the idler bearing when used with a 16 tooth pulley.
2 - It is designed to use M4x25 socket cap screws and M4 nuts (since the motor mount threads on my RigidBot came stripped).
3 - It has two gaskets printed in NinjaFlex and/or Polyflex for sound dampening. The flat gasket is 1mm thick, but you can rescale it to whatever thickness you like.
You will need to mirror the part if using on the Y-axis.
The black gasket on the left was printed in PolyFlex, the red gasket on the right in NinjaFlex.
edit: Added another version of the mount, one without the flexible parts (I switched to this one to use with Astrosyn dampers). I used Taulman Bridge nylon, but it should work in other materials. This version will require support material to print.
edit 2: Turns out the Astrosyn dampers tilted more than I liked under tension, so I switched to a new mount that merges the design from the first two versions of the mount (version 3).
