This is a filament spool holder to mount to a 4040 extrusion - or really anything you can screw into really if you cut of the little nose on the arm in the slicer ...
(Which is there to stabilize the arm mounted on the 4040 extrusion but I'm not sure how much it really does ...)
The holder itself is inspired by butchjas model here:

But it is a different model and not compatible in any way!
Bearings are cheap 6200 (10mm ID, 30mm OD, 9mm wide). You can use some kind os rod but I use a printed pin. The pin is a bit loose so you might want to scale it up by a percent or two - I simply used superglue to cover my crimes and fingertips.
