Rotor-shaped coasters have been done before, but never like this! The detail on these coasters is stunning…right down to the gear teeth, apex seal slots, corner seals, side seals, and even oil control ring seals. Made from high-quality, impact-resistant PLA, these coasters are solid, won’t move around when you lift your drink, and will look amazing on your table! Comes in a set of 4. So yeah, we call this the 26B set. Did we mention you really need these?
