Multi-Sided dice with inlaid numbers.
They should probably be printed solid to give them some weight. I would also print them with line widths of 0.3 mm if you are using a 0.4 mm nozzle, this will make the text look much better. Ironing also helps with the top layers.
I have include 4, 6, 8, 10, 12, and 20 sided dice.
The text file are separated so you can print them in a different color than the dice.
Update: I added a 10 sided percent die.
Update 2: I saw a couple comments that the dice are small. I ordered some from amazon and compared them and ideed they were small except for the D6. I remodled them and made them match the ones I purchased. The original size models are still available as are the new larger dice. There are new profiles as well, one for single color and two for multi color. One multi color where the dice are individual so you can print just the ones you want, but cant do more than one with adaptive layers on, and the other with adaptive layers and all the dice as a single object.
