This is a stackable rack system for storing your filament spools and boxes.

The assembly of the rack is pretty self-explanatory through the pictures. 

The individual sections are glued together and can be repeated upwards as often as required. To do this, simply stack several of the middle sections on top of each other.

The holes for the wooden rods are 20mm and tubes or similar can of course be used instead of wood.

The shelf in the pictures is 50cm wide and 7 rolls can be stored on each level. The width can of course be adjusted and, if necessary, equipped with a third support level.

If you only use the three bases, the height is approx. 50 cm high and 19 cm deep without castors. It is designed for castors with a diameter of 20cm but others could also fit. 

The middle section requires an installation space of 245 cm and fits perfectly on a Bambulab
