Finally finished making a custom Catan table / board! I used the free game piece files that Glowforge posted a while ago, but modified them to fit my needs, the modified files are in the link below.
I had a metal end table frame and decided to design a removable Catan board to go with the custom game pieces. The box in the center to hold all of the pieces is also removable so I can take it all with me without bringing the table frame.
Yep! The top is three layers, and the mounting parts have an overhang piece that twists onto the top so it’s kinda locked in place. The link at the bottom of the post has a lot more pictures and info on how it was made
