As a part of a self-made tradition: entering the competition with Skeleton themed models!
This time was a pretty easy modelling: Already had SVG with the bones silhouette from previous project, so needed to measure a regular coaster size & cut it in needed shape!
8X8 cm, 3mm heigh (2.2mm the bones, 0.8mm only the ring - for changing color)
You can also print it with colour change function - just change the colour on 2.2mm (that way the outside ring will be in different colour)
