Hydra/SHIELD coaster

I really liked the SHIELD and Hydra emblems by tekkou (https://www.thingiverse.com/thing:2857756) and fancied a two sided drinks coaster.

so I designed this

due to tolerance issues, I find that if you print the outer ring at 100.7% scale, it requires no fiddling around afterwards.

there is a small notch in each emblem, and a matching ridge in the outer ring - this ensures that the logos are exactly lined up on each side.

they are the right size to hold a normal cup.

flip them to show your allegiance......................................
