D20 Coaster

Edit 5/9/2019: I finally uploaded a version with a backing on it. Without the backing condensation would roll down over the coaster onto the table you were trying to protect. You don't need this coaster to be the full 5mm thick, so you can reduce Z component to 60% to make it 3mm.

I wanted coasters to put on my game table so these are pretty handy. I used TPU filament and printed them out with out too much problem.
