I've got almost 50-odd filament swatches and I wanted larger and fewer boxes to store all of them neatly.
Each tray holds 30 swatches. The swatch model I'm using is from thingiverse u/platini76, cheers to him. I reckon similar remixes of this model should fit fine.
I originally modelled the tolerances to fit my Bambulab A1 mini, so you may need to re-scale it if you are printing on any other printer model.
15% infill
0.28mm layer height
Gyroid pattern.
The author marked this model as their own original creation.
