Firefly / Serenity coaster holder set with 5 coasters

I created this coaster set with holder as a Christmas gift for a friend who is a fan of the Firefly TV show and Serenity movie.  The coasters can be printed with no raft and no supports.  The coaster holder needs supports for the letters on the front.  I have another version where the Serenity logo is negative space, but removing the supports from that version is very difficult.
