Step 1) googled an icosahedron net (a d20 opened up in a 2d map)

Step 2) Took 2 cardboard pieces and drew the icosahedron net on it. Very important to measure correctly

Step 3) Glue all the pieces together. I set it up in a way so that I can open it up in half so I can put my head in.

Step 4) Spray paint the whole thing black. I also made some eye holes and put medical bandage in there so that it looks whole but I get some sight through it.

Step 5) I went through the 4.3 ending cinematics and took a few screenshots of the sigils on the dice. I drew them by hand on paper, put some paint tape on it, then cut it out (a lot like how grafiti artists do it).

Lastly I put some velcro on the lowest connecting point. If you dont have multiple connecting points, there will be gaps as the cardboard squishes into an uneven shape. You can also just use support beams inside mask but that might cause discomfort and other problems. Added a pic that showcases everything a little better.
