Tokens for your RPG, with a hollow space to add washers for extra weight! I designed these as Devil's Luck tokens for Pirate Borg, but I'm working on other designs for games like Draw Steel, Fabula Ultima, and D&D. 

I used a 3/16 x 1" washer, and I've included the fully parameterized F3D so you can adjust the washer size as needed. The model has a built-in support structure attached to the Frame model, with a notch in the side of the model to wedge a flathead screwdriver into.
