This spool holder is for the Printed Solid enclosure: https://www.printedsolid.com/products/next-gen-safety-enclosure-for-prusa-style-printers

This is an evolution of this spool holder (https://www.printables.com/model/206236-spool-holder-for-printed-solid-enclosure), with a big reduction in rotation friction by having the spool spin on bearings instead of sliding on a supporting shaft.

In addition to the two printed parts, you'll need a ~113mm long M6 threaded rod, two M6 nuts, and two 696 bearings. 

I recommend printing the parts out of PETG, ASA, or other plastics with more temperature resistance than PLA. Also, print with a brim.

Here's the Onshape CAD model in case you want to copy and modify it: https://cad.onshape.com/documents/22cb06e9596a85f495c3ba4a/w/177f72f66219baa6eee97515/e/c0b99e3b331411522284d059?renderMode=0&uiState=64a1a0179d16c55a5cfee452
