Assembly

1. Print the dice wheel first. Pick two colors you like, preferably something with contrast. 
2. Fit a 10x3x4 (623ZZ) rotary bearing in the center of the wheel
3. Press fit a M3 nut into the hexagonal hole on the matching half of the case. Push an M3x12 bolt through the other half.
4. Put the bolt side face down, threaded portion facing up, and place the disc on top of it, aligning the bearing with the hole. The D12 side should be facing down, you should see the D20 side facing up
5. Put the nut side on top, and then hold the two pieces together, and screw the nut down, joining it into the bolt. Once the fit is fast, back the screw off slightly. Adjust till the disc spins freely
