This is a D12 intended for randomly rolling a D&D class. It is a remix from someone's blank d12, all I did was add the markings, but I cannot remember whom I remixed it from since I started it 2 years ago, forgot about it, and finished it today when I re-discovered it buried in my Tinkercad account. Feel free to use it, but you may want to scale it down a bit, it isn't small.

Edit: Added another version that replaces the Multi face with a Warlock face. Sadly, due to differences in the available fonts on Tinkercad, I was unable to match the original font.
