Looking for large 12 sided dice that I can have custom printing on the sides, or blank and I can put a design on there myself. Large = 3-4" diameter. The largest blank ones I've been able to find online are 1.25" (32mm) from a guy on ebay.

My google searches have turned up nothing, and i'm starting to think i'll need to go to a custom 3d printing shop.

Places to look?
