Best Filament Spool Holder With Keyway

thingiverse

. Bits:- I used Stainless 8 x 90mm socket head bolt with 2 of stainless washers 8 x 16 x 1.25mm and a NY lock nut, FYI bolt length not include head. You use whatever you want 2 skateboard bearings 22 x 8 x 7mm 608zz. Be sure to clean artifacts and elephant foot from bearing inserter before pushing it in the hole (test first). Put a washer on the bolt then the inserter, use the bolt as a guide. The bearing in the cone needs a washer both sides to give the bearing clearance. I have a few of these printed and have them fitted to the spools I’m using, change them out by undoing a large nut on the bracket assembly, change out the whole thing. Don't know who designed the initial style, but I liked the look, so this was designed around that look.
