Space zombies Building Pixel (Cube)

Inspired by some simple wooden cubes :).

The goal is to have a single piece providing the opportunity to build everything, in a very cubic and fractal style. It's sculpted from a 100x100x100 mm cube with 5mm diameter assembly holes. Drop one alone, it's a small pyramid, or two together and it's a opened pillbox. 4 together upside down for a bunker, line them for an edged defensive wall or stack them to create towers. arches, gates, always with cover and firing positions. Scale them down to create steps, anti tank defenses, ect... supportless like always. I'll add later a second semi circular piece acting as catwalk and wall/door. Just grab some graph paper and start drawing., or keep things modular, your call.

You can actually even create minecraft style hills with a lot of small ones, have fun.

Looked for a design that would be practical overall and easy and quick to cut in and from a mass, better fitting a new generation of machines being a bit more dynamic and concerned abo
