Modeled a large d20 to print just for fun. Actually works quite well. I would avoid rolling it on any surface you don't want to damage (roll it on carpet).

There are two models. One large, one not so large. The big one has been affectionally named 'The Chonker' while I call the smaller one 'The Softball Special'

Printed on CR6SE with PLA Supports needed for the some of the embossed numbers
