Star Trek Combadge Coaster

I created coasters with Star Trek Combadges The size is 100 x 100 mm and 4mm thik. I added a 1mm cork Layer on the back of the coaster.Thanks to the cork, the coaster on the table is not quite as slippery.I bought 1mm cork tiles on Amazon. These are the tiles I bought, they are Self-Adhesive.https://www.amazon.de/dp/B07S188DRJ?ref=ppx_yo2ov_dt_b_product_details&th=1 Here you find the coaster holder.https://makerworld.com/de/models/69313#profileId-73582 Boost Me
