Dynam Excalibur - Motor mount enforcement
thingiverse
This mount gets more stability from the torque of these big motors. You can see online that some users had bad experiences with broken mounts while flying. I've changed the inner diameter to fit best with the prop holder. The air intakes now have chamfers for better air circulation. More material has been added against the original one, increasing stability a lot. The screw positions of the motor against the prop holder aluminum part don't match properly. You'll need to grind two inner screws a bit, as shown in the pictures. The screws are DIN912 M3x10mm hex.
