The PERFECT filament spool holder

This spoolholder is very efficient and easy to use and print. One side uses only two different 3D-files printed twice, two 608 bearings and two M3 bolts and nuts. The spoolholder is very sturdy, it keeps the bearings in place and aligned and the shape of the rollers helps to center the spoolholder during motion.

Update:

• 2025-02-01: Added new roller with flat surface instead of V-shaped.
• 2025-02-01: Added print profiles for MK4 & MK4S

Printsettings

I prefer to make the spoolholder a bit more beefy and heavy to make sure it holds up and stays in place.

Needed for complete spoolholder

4x “part 1” i.e the sides

4x “part 2” i.e the rollers

4x 608 ball bearings

4x M3x15 Screws

4x M3 Nuts

Assembly

When all the parts are printed you are ready to assemble.

1. Start by pressing the bearing into the rollers. The rollers are designed with an edge on one side to keep the bearing in place and centered.
2. Slide the bearing on to the “peg” on each of the sides.
3. While holding the two sides together, insert the nuts as far into the hexagonal hole as possible
4. Insert the screws into the cylindrical hole and once everything is alinged, tighten the screws.
