Half Mug Coaster

This coaster is inspired by a coaster designed by Ethan Wu, which in turn was inspired by a coaster he saw in Japan. Wanted something for my ½ mug which was gifted to me a while back so tried my best to make a similar design in TinkerCad. Still learning but think it came out ok for a first try. Printed in PLA, inner diameter is 108mm if I remember it correctly. Boost MeSaving for an AMS - Doubt I'll get there anytime soon, but wouldn't mind a boost if you have one spare! Thank you!
