Spool holder for all common 0.5-1kg filament rolls. This is screwed directly to the surface with 4 countersunk screws.

4 ball bearings of type 626ZZ are required - inner diameter 6mm, outer diameter 19mm and width 6mm. These must then be carefully pressed into the corresponding positions for assembly.

To ensure a perfect surface on the rollers, the rollers consist of two parts.
First, the two disks (Part 1) must be printed, which must then be inserted during the printing of Part 2.

A print stop can be clamped in the slicer for this purpose. After printing, the slices can then be fixed in place with adhesive.
