K1 Bearing Spool Holder - fix version

Fixed version of the spool holder with bearing for Creality K1.

The original version had a tendency to lock the bearings, perhaps due to the cylinder reinforcement coming against the inner race of the bearing.
A rim was also missing on the mounting side, which did not prevent the spool from rubbing against it.

This remix fixes both issues encountered above.

I also included a toothed version of the assembly, which makes installation easier.

I also offer a narrower version for smaller spaces.

• refinement of the cylinder reinforcements
• addition of edge on the mounting side
• toothed version of the assembly
