Creality K1 / K1C / K1 Max Spool Roller v2

Version 2 of my original Spool Roller. I had a few people comment that they were worried about the spool falling off. I have never had a spool fall of the original spool roller, but I wanted to find a way to address the concerns, while also keeping the aesthetic of the original.

The main difference from the original model is that the roller slides through the back of the holder. The plug is keyed with wedges to allow it to be pushed in to keep the roller secure.
Like the original, the Spool Holder is oriented standing up with the coupler on the bed, this allows for the least amount of supports needed. You'll need two of the Roller file to make the whole roller. Supports are needed for the Spool Holder, and optional for the Roller. The square key peg and the plug print flat.

Things You'll Need:

2x 608ZZ Bearings

I used Orca to slice the model, so keep in mind that these are the settings that worked for me and YMMV.
