Snapmaker 2 Spool Holder Sleeve

I use a Snapmaker 2 A320 with the enclosure and decided to mount my spool holder inside of the enclosure. I was running into an issue where the PLA spool was trying to rotate on the bar and then jumping while feeding out.

Looking at other ideas for storing the spools in dry boxes on axles that were sized to fit the spool I decided to make my own sleeve to fit over the bar that smooths out the feed racking.

The cap slips knob slips inside of the spool to rest flush against each other.

This was designed in Tinkercad No supports are required and I will try to upload the raw CAD file if you want to resize the spool for custom spool hole sizes.
