Spool holder for Ender 3 with ball bearings

Nice and smoothly working spool holder with two pcs ball bearings.

Because I have 3D printer Ender only 2 months I designed spool adapter (spool53_long/short) for filament spools which I only have.

I buyed on flea market 2 pcs of ball bearing (buy cheaply :-D ) and after that I designed this spool holder.

2pcs Ball bearing - shaft 10mm, housing ID 26mm
