Portal Inspired Coaster Set

A set of coasters inspired by my favorite puzzle game, Portal!  This set includes a companion cube, sentry turret, and the Aperture logo with a cake.

Coasters are all 100mm diameter.  Sentry turret and cake logo are 5mm tall, while the companion cube is 6mm to allow for some more depth on the cube corners for chamfers.

Let me know if you have suggestions for these or other sets.
