Star Trek TOS Insignia Coaster

I needed a better coaster than what I had, I like Star Trek...so I made this. As is, it can accommodate bottles and glasses with a width of up the 70 mm. It also has a high lip that wraps around the bottom of your bottle that should catch any moisture that might condense and drip down. It has worked great so far.

The emblem is the command insignia from the original series.I might rework this using other Star Trek insignia (Science, medical, or engineering) or feel free to remix it.
