Hanging Spool Holder

UPDATE: Added a bit more play to the rollers. Added a cap to the bearing stud to hold bearings in place. Look for the V2 roller and stud files to make this change.

I couldn't find a spool holder that met the requirements for exactly what I was looking for, so I designed my own. Three of the main requirements I was looking for are as follows:

1. Vertical hanging to mount inside my enclosure (rather than on top) and remove the weight from my printer frame.
2. Uses some form of roller or bearings rather than being dragged over a fixed arm like the basic spool holders.
3.Designed in a way that a spool (especially new ones) won't unwind and tangle.

In addition it feeds straight down so if something jerks on the filament for some reason it's not going anywhere.

For flexibility I made it so it could be side mounted or an included adapter can be printed for a rear mount.

Rollers are easily removable to fit larger spools up to 100mm wide.
