Ender 3 Universal Spool Holder

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.
