I have dice that are slightly larger than standard, and I had a hard time finding a dice box model that fit, so I made one!

Lid stays together using 6mm x 2mm magnets, with press fit holes. The lid operates as a dice tray. I have also included a bottom that doesn't have slots for the dice, so you can use it for other things, like multiple sets of smaller dice, tokens, etc.

This is made with OpenSCAD (free), and I have included the source file. There are variables at the top that can be modified to account for different sized dice or magnets, or if you want to use a custom logo svg instead of the free d20 logo (sourced from svg4k https://svg4k.com/svg-for_cricut-and-silhouette/d20-dice-isometric-svg-free/)

In the future I plan to make some middle sections that can be attached modularly, giving the option of having multiple dice sets, or dice and tokens, etc. Not sure when I will get around to this, but I have the project on github here: https://github.com/elijahgill/dicebox
