Want to make your own die. Now you can. Get each side dyed different colours, configure the dye to prefer one side over another or get the shell made up of a different material then the sides. The options are limitless(Well 1,330,255,872 combinations if you keep to standard die numbering and do not cut the alignment tabs off.).
What you need is the frame and 6 faces. Assembled them together by pushing the faces into the frame.
Fair sides are not available individually because you can make a fair die out of the loaded sides by arranging in the order shown on the loaded faces rendering.
For the loaded dies each side can be place in 1 of 4 ways. If you want to make the die role more often to 1 side then another place the heavy side away from the number you want it to roll. Placing the weights opposite each other will cancel there effect out. Placing 4 together will shift the center of gravity 499um towards that side.Photo provided courtesy of dicecollector.com
