Stair Cubes - Corner Groups

I've decided to release all the files from my 2017 Kickstarter: Dunkley Designs - 3D Printable Pyramid & Ziggurat Terrain. 3D Print your own Pyramid or Ziggurat, using a cube based, locking system.

When I created this system, I used triangular pins for horizontal connections and diamond pins for vertical connections. Please don't ask me to update these with OpenLock or other connection systems; I have no intention of changing these files. Sorry.
