I removed the end on the small side to reduce the needed place on the Heat bed.
I also fix the issue with the wrong scale.
To use this part, it's needed to add:
- 4x DIN625 Type 608 (2RS or ZZ) bearing role (you can also add 4 additional bearing roles to support smaller spools, too.)
- 4x M8x30mm screw
4x M8 nut
- optional a cork or rubber mate
