Aboriginal Flag Coaster

The model was made of 4 parts. Bottom layer is full black at 1.5mm thickness.The other 3 parts are 1.5mm thick with the Red and Black 1/2 ring and the Yellow center circle.The Holder I found on Thingiverse (https://www.thingiverse.com/thing:3643296).Holder was painted in the slicer to compliment the coasters.Coaster and Holder have felt glued to the base of each item.My friend was over the moon as they have never seen just the flag coaster.
