The provided border system for DUNGEON BLOCKS was designed to support square or rectangular grid setups only.

I've created a ‘half lapped’ system which uses less material and time to print and opens up a world of different options for custom grid layouts.

Commercial use is forbidden!

** UPDATE: 20241013

I have uploaded a v2 of the outside border. While the original version fit the grids perfectly, it was actually causing some binding between the tiles set into the grids causing uneven floors and making it hard to ‘open’ doors. I apologize to anyone who printed these out already. v2 of the outside corners has alleviated this issue while still enabling freedom to design non-rectangular DB maps.
