This is not a 2D model, the coaster is 2mm thick with a 1mm emboss design. It was originally 5mm until I found out that'd be a 7 hour print, so I squeezed it down to two. I was inspired by the idea of putting stars on a coaster but that was too much in such a small space. I opted for the solar system and that reminded me of how science is based on the science of yesterday, which led me to the Earthcentric solar sysem. The print profile prints the model with a 0.2mm nozzle and at 150% size in order to get a good, clean print. I had to use a support block to make sure it only prints 1 layer of the secondary color.
