I already had a JAWong's Catan design printed (https://www.thingiverse.com/thing:26979/files) and wanted to enjoy the benefits of the magnetic base & system. So I modified fq97's catan base to split into 2 and friction-fit together, allowing me to place the original catan tile between the 2 base pieces. It's a bit more effort to print & assemble, but it meant i could retain my original catan tiles.
