This is a light glyph from the owl house designed into a coaster. I based my model on the design by Aftermath_80085 on thingiverse: https://www.thingiverse.com/thing:4571119, but I remixed it into a coaster design. You can change the filament partway through to give it a cool look. The inner diameter of the part where the cup sits is about 72.5mm which is the perfect size for all the cups I tried it with. (I designed this for my sister because she is a fan of the owl house and needed a coaster, but you are welcome to make and remix it)
