Dice Holder

A customizable dice holder. Enter how many dice you want to carry and the size of each die, and get a sleeve to carry your dice with. Optional (advanced) parameters include tolerance (extra room between a die and another die, or the wall) and wall thickness.
The current iteration is working pretty well for me, but it might not work for all combinations of parameters. That's why I have left it as "in progress". Let me know what worked/didn't work for you and I'll see if I can improve on it.
