Attached are the entire file (Base and pieces), A full piece .stl, Full base .stl, Half base .stl, and each individual piece (11 parts)
The base is 285mm x 114mm, just glue both halves together if you need!
Print time for the base was 7 hours (2 halves) and pieces are 12 hours. I'd recommend at least 3 sets of pieces as 2 people can "easily" complete the game.
The base is 1" and the pieces are 0.98" so the pieces fit in very nice!
This is my first upload! Enjoy.
