This is a 1€ coin coaster or toy.

I printed it using lightning infill at 10%, which is why the silver part doesn’t look as good as it should. I’ve updated the slicer project, so it should print properly for you.

Since I have a lot of gold filament and nothing specific to use it for, I printed most of the coin in gold and only used silver where needed. You can change this in the slicer if you prefer a different setup.
