I modelled the Attack on Titan Scout Regiment insignia for a project, and thought it would make a cool dice box, so here it is.
I modelled it to fit my dice with some breathing room, so hopefully most near-standard sized dice should fit.
There are cut-outs for 6mmx2mm magnets in the lid and in the base.
The letters in the base are their own solid bodies, so you can easily set their filament color and not need to use filament painting (since its buggy and bad at text sometimes). Or you could delete them to still show the lettering but without needing a color change.
When filament painting the lid, make sure to paint the sides of the colored sections to get more than 1 layer of the color, or use the 3mf file I uploaded where its already fully painted.
The author marked this model as their own original creation.
