I'm experimenting with making my own #dice. I've been #3DPrinting some, and just tried using a mold and epoxy. I didn't have my mold release agent yet, but I tried anyway, and it didn't want to come out. I wound up splitting it in half while trying to get the mold open. I also think I need to put tape around the seam of the mold to avoid leaking some epoxy, in addition to the release spray.
Other than that, I'm impressed with how it came out. The color looks good in the areas that came out well. It came out good enough that I can see the numbers and the layer lines from the printed mold.
