Mac Pro Cheese Grater Coaster

This is my version of the new Mac Pro 'cheese grater' grille, in the form of drinks coasters.

If you make these in PLA, remember that hot drinks may deform the plastic as PLA becomes soft at relatively low temperatures. I've tested with hot tea in a typical mug and it was fine. In the mug pictured, I observed a small amount of deformation due to the smaller footprint of the mug. You have been warned! :)

Coaster at 100% scale measures 82mm across the flats, 91mm across the corners.
