Filament spool holder with duel bearings. I designed this solid holder because printed filament holders will likely always eventually break. Usually at the pivot point where the most weight is applied. My printed holder lasted nearly 5 years before it broke, fell onto the bed and ruined a 9 hour print at 96% complete.
This holder uses a 120x8mm bolt secured the the original ender spool holder upright with an 8mm hole drilled just below the large hole. With 2 standard bearings and 2 printed spacers either side. It works better than than the old printed holder and has zero change of breaking.
List of items:
1 120x8mm bolt (or threaded rod)
2 Standard bearings, 608ZZ bearings (22mm OD x 8mm ID)
2 nuts (Extra self locking nut if using threaded rod)
2 Washers
