Three player chess board
thingiverse
You'll need to print the board three times, and you can adjust it to your liking. Unfortunately, you'll have to find a chess set and eyeball the size yourself. Print Settings: Printer: Mono Price Select Mini Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.1 Infill: 20 Notes: I used 0.1 resolution, but you could probably get away with 0.2. I did use a raft, but it's really up to you.
