Topographic Michigan Coaster

This is a coaster featuring a topographic map of the state of Michigan and surrounding great lakes. I added color changes to the gcode to make each layer a different color. If making coasters, I highly recommend filling the cavity in the top of the coasters with a clear 2-part casting epoxy. This will create a smooth, level, heat-resistant surface in the center of the coasters (this is important as a warm coffee mug can melt or warp PLA).
