Wanted a case/storage for the awesome Catan 2.0 game by Dakanzla, found this and tweaked it a little :

• removed the sides so they are flat (easier/faster printing)
• removed the holes/ pins to connect them together and changed them into holes for magnets(8x3)
• removed sharp corners
• split them into 4 pieces
• changed outer dimension a bit (kept the size of placements/ inner dimentions)

If you want to support my work, you can buy me a coffee.
