Just wanted to share this part that I made that allowed me to use 63mm motors on my stock evolve motor mounts. This is a spacer that goes between the motor and the motor mount which creates more surface area for the parts to contact. It can also add a nice little bit of an accent color. I haven’t stress tested this too much, as I’m not a heavy duty user, but from my tests it seems to work perfectly and my belts haven’t lost any tension. Here’s the part:
Please note that I am only able to mount each motor using two of the four mounting screws because of the different evolve mounting dimensions, but this seems to still work fine for me and I haven’t run into any issues.
