This is a safety cap for the MPCNC525 motor's rotating parts.
It will prevent you or others to put fingers accidentally between the rotating parts.
There is a small (6mm) gap to push the motor wires thru.
I tested it, it will fit every MPCNC machine with the newer motor mounts on it.
NOTE. The picture's of the assembly are slightly different, because of the motorwire connector. I will post the motorwireconnector as soon as possible. But it is not needed if you dont want the connector..
Print flat or straight up. I printed this flat with the hollow side downwards +don't forget support!
I didn't printed this straight up, but then you do need less support (just between the rings).
I guess printing straight up doesn't need to be a problem.
