Ender 3 Universal Spool Holder

thingiverse

I modified the original spool holder model to use M3 screws and 608 bearings. I also added a ring for the bearings to center the spool. ## **Required Materials:** - 4x 608 Ball Bearing - 4x M3x16 Bolt - 4x M3 Nut You also need the two M5 bolts and T-slot nuts from the original spool holder. ## **Assembly:** 1. Put the rings around the bearings 2. Optionally use a 3mm drill to widen the holes in the spacers 3. Put two spacers in each bearing 4. Put each bearing with spacers in a holder and secure it with an M3 screw and nut. 5. Use the two M5 bolts and T-slot nuts from the original spool holder to attach the new holders on the top in place of the old one.
