I do not own a 3D-printer, otherwise I would have made this from plastic.
As it is, it had to be made the old-fashioned way, scratch-built from card-stock.
This was made for the Star Wars Armada Damage Deck (it is very tall, because I have two starter sets, and dunno if I am going to use both at a later point).
I am already working on an improved design (not the final one though), involving more glue, and possibly less scotch tape, for my Strange Aeons Solo Play Deck.
My blog contains a few more details on the matter - but I intend to do a more comprehensive guide later - so don't be disappointed by the lack of detailed information at this point.
