Motor Mount Tensioner Arm

[Billy-d-Kidd]

Excellent work on this project. I did notice a thing or two while building it.
For the heat set insert version, would it be possible to add a short M5 insert where the M5 tensioner ring bolt goes into the motor mount? This way when loosening the belt you don't go to far and that M5 nut fall out. Might also be able to add a spring between the mount and the transmission body or the transmission body and the tensioner ring, to maintain tension while loosening or tightening, thus allowing the motor mount to move accordingly without having to get fingers in there and push or pull the motor mount itself. That gets difficult with the printer inside an enclosure.
