Ender 3 Spool Holder using Airsoft BB Bearings
Description
I designed this based on the design from mjoaris which uses metal bearings but I didn't want to buy them and I already had airsoft BBs. This spool holder fits on the ender 3, ender 3 pro, and possibly other reality products but I don't have any others to test it on. There are two versions of the "Holder." "Holder_any_angle.stl" is meant for a situation where the angle of the metal channel that holds the spool holder is not vertical. You will need: -Nut2.stl (may need to be scaled up by 1-3% in X and Y due to different printer tolerances.) -Roller2.stl (or use Roller3.3mf which has support blockers that might be needed to prevent the nubs from being broken when removing supports. I broke one of the nubs off twice and had to reprint it.) -2x Ring2.stl -Holder3.stl or Holder_any_angle.stl -12x 6mm Airsoft BBs
