Create your own «Rediced» D20

I’ve found a solution for that: the filament scraps generated by supports, color changes, or calibration can be recycled and reused. “Rediced” are D20 dice created by compression molding using leftover material.

WARNING: The following process involves high temperatures that can cause burns. It may also release unhealthy fumes, so this should only be done in well-ventilated areas. Please take appropriate safety precautions. No liability is accepted for injuries or damages!

Before preparing the material, set up the press mold. Align parts A and B so the opening faces upwards. Then insert both parts into part C until they sit firmly (see illustration: A and C together, B in between).
Optionally, you can grease the mold (e.g., with Vaseline) to make it easier to release the dice later.

Place your selected scraps into the muffin mold and heat them using a heat gun (or in the oven) until they become soft. Note: The muffin mold will also get hot! If using a heat gun, work on a non-flammable surface.

Heat the material only until it is pliable, not fully liquid. Shape the mass so it fits into the press opening. If it hardens again, simply reheat it. Caution: The material and the muffin mold are very hot! Wear gloves to avoid burns.

Shape the mass so it fits into the top opening of the press. If needed, push it down with your fingers – again, carefully, it’s hot!

Then: press it! Use the “lid” of the press mold to compact the material. Press for a few seconds and then let it cool for 1–2 minutes.

Once the dice has cooled, open the mold and remove it. I achieved the best results while it was still lukewarm – this made it easier to remove without losing shape.
Trim off any excess material and paint the numbers if you like.
