Here’s yet another system that can be used to make your own games, miniatures terrain, RPG maps, and more. CreatorBlocks is a set of modular pieces that can be 3D printed and assembled in a multitude of fashions. The system is very flexible, with both square and hex tiles plus supporting pieces for each. There’s walls, floors, different textures, and a lot of other customizable features.
The best part? The system is open source, so you can feel free to modify and of the pieces in a way you see fit. Designer Anthony Davila has put everything you need to get started up on Thingiverse.
I’ve got a few pieces queued up to print now so I can see how it all fits together.
