I really liked this tray for the helix dice tower:
So I added the Mutant Year Zero logo to it, as this is the game I'm playing with my group. I vectorized the logo from the official character sheet and imported it into tinkercad. Provided the STL for that as well if you want to use it otherwise.
I printed it with two filament change codes so I could use a different filament for two logo layers and then return to the other color.
The author remixed this model.
