Maiden voyage of my #tarmo5r . It ran for about 2 minutes before the motor sheared off the rotary gear. The part itself was modified to account for an 11mm coupler, but on top of that, only the gear teeth were holding on to the coupler. The actual part has a huge space to account for larger motor shafts but it really weakened the structure.

I'm reprinting the part with an 11mm coupler hole and 100% infill. I also closed the gap.
