This Foundry module is a collection of custom dice sets for use with Dice So Nice.
Plug https://raw.githubusercontent.com/ben/bensdice/main/module.json into the module installer in the Foundry setup menu.
I'm not super good with Blender, but I have figured out how to export files so that Dice So Nice will use them. Head over to this document if you want to know how to make this your own.
