D-20 with the Home logo from the Dial Home Devices in Stargate Atlantis and Stargate SG-1 replacing the 20. make sure the die is flat against the surface when you go to print. If the file loads point up, please let me know, and i will attempt to fix it. Normal scaling is 25 mm tall Once you have it printed out, use some nail polish to fill in the numbers. Don't worry about being a little messy, because you can use acetone after the polish to wipe it off where you don't want the polish. The acetone also seemed to smooth the surface of my die rather significantly. You can hardly tell, at least at a cursory examination, that it was printed.
