Cork Coaster

I recently started my 3D printing journey, and this is my very first upload to MakerWorld! A friend asked me to design a pair of coasters with built-in bottle openers. He gave me a rough description of what he had in mind, and this is what I came up with.I printed two of them so far, and they turned out great! Unfortunately, the third one didn’t come out as clean—the supports were extremely difficult to remove and left it a bit messy. Still, I’m really happy with how the overall design looks and works. If you got any improvements or ideas for the supports please share them with me! These are the following materials that I have added.
