Ender 3 Spool Holder Mod

thingiverse

I recently purchased an Ender 3 Pro on auction. Some of the filament spools I had, had a smaller hole so the standard Ender 3 Spool holder would not fit at all. (See the fiirst 2 pics. ) So I designed this new rod that is thinner but uses the fixing nut of the original Ender 3 spool holder as well as a nut to keep the spool in place. (See pic 3) The rod screws down exactly like the original one except I can now load my spools with the smaller central hole. The rod should be printed with > 50% infill to make it strong and printed vertically. Supports are needed only on the bottom most part where the original Ender nut is screwed on. Important: Do not use a RAFT ever. But use a BRIM of 4 mm touching the model for stability. The nut can be printed with 20% infill and no supports. I have included my Sketchup files for anyone who needs to mod this.
