Ender 3 spool holder

hello !

I designed a simple spool holder for Ender 3 in 3 pieces following the most common ideas we can find here !
it's designed to be used with 4 624ZZ bearings (4x13x5mm). They are mounted tight so only the exterior part of the bearing is rotating.

The spool holder can adapt to different spool sizes.

Let me know if it works for you or if it needs modifications.
