I first used a model that was meant to be put right on the machine. But, the stuff inside the box shook during the calibration and made a lot of noise. So, I made a new model that you stick on the side of the machine instead. To keep it from moving during the calibration, just stick some double-sided tape under the box and attach it to the table, not the machine.

Universal Filament Storage / Spool Rack v2

Designing these models is HARD, and sharing them makes it harder. Creating these designs takes substantial time and effort, involving a lot of testing and a significant amount of filament wasted until the perfect design is achieved. While making models for my own use is easier, sharing them with others requires additional work. The designs need to be more foolproof and universal, and I have to create all the profiles, take pictures, and write descriptions and instructions. Your support would be greatly appreciated. Boosting my models would really help me continue sharing these designs with you. Thank you!
