IKEA lack printer case spool holder

in addition to the lack cabinet I made a spool holder for the Prusa to take up to 4 spools of filament, because the MMU.

The total amount could be up to 4 kg of filament, plus the spools itself and the hangers components.
That's why I recommend an enforced top instead of the cheap lack tabletop.

Then you can screw it under the top and hang on the required filaments.

Use the base sockets, guide a 530mm long aluminum or steel rod with 10mm diameter.
The single hanger has two bearings within, 6000 type, and another short (130-135mm) rod to take the spool.

3 options at all for the sizes: normal, xxs and xl

> normal one as shown in the photo
> small version short and a minimal fillet
> larger version that would fit completely with the stock prusa spool (don't know if the prusament spool is the same, old was out 200mm diameter and inner 50mm, width of 88mm), where the spool collides with the holder in the fillet.

The load of 1kg let one of my first parts broke slightly.
