Filament Spool Holder

Needed a quick and easy way to get spool to roll freely. Used 2 SC10UU Linear Motion Ball Bearing, a couple rubber bands, and an 3/8 inch aluminum rod from the hardware store to achieve this. i believe the inner diameter of the spool is ~55 mm.

Its kinda a remix in that i used the basic concept for one of tswaehn models as reference for this. I just wanted to use my bearings and the stuff I already had laying around
