Ender 3 Pro Spool Adaptor

Simple spool adaptor to center the spool and prevent abrupt hopping. This goes over the stock hanger preventing abrupt spool rotations as the extruder is trying to pull it. This greatly reduces the load for the extruder to pull the filament. It has a lip on it so the spool is restrained on the hanger. The ID of the adaptor is 0.03" bigger than the stock hanger lip.

This really smooths out the load on the extruder. Let me know if you have any dimensional change requests and i'll make a revised model.
