Cricut (or other) roll holder that fits inside an IKEA Kallax cube. Two different capacities: 28 roll holder that needs to be assembled a certain way (the panel has indicator arrows to ensure proper alignment) or a 20 roll holder that can be assembled in any way, no mistakes. It is 250mm for the regular blade and 190mm for the short blade in depth and it can accommodate up to 50mm rolls. Assembly is simple with the included printed screws and 4mm wrench. However, if the screws are troublesome you can also just push it in for a press fit assembly. It is designed to hide the screws and assemble easily with everything sitting flush. The panel has to be printed 8 times but everything else is a single print. Choose the 7- or 5-hole variant and print away. The panels do use supports and I recommend a support filament for ease of removal. However, because of the way it's printed and the countersink the support takes up the space and is flush to the face of the panel. Use one of the screws to punch out the support.
