90mm Coaster Base

This is a 90mm coaster base that I designed for making custom coasters. It was designed in fusion 360. I take black and white clipart and use Microsoft 3D Builder to extrude the clipart. I then center it on the coaster and set the bottom height at 3.5mm. Next I subtract the clipart and have a coaster with an embossed image 0.5mm below the top surface.
