Add these diagonal/curved wall pieces to give your cave/cavern a more natural vibe.

I remixed the original tiles adding an Openlock triplex base you can click the tiles together in a limitless configuration of your choice. This way you can build the terrain easily and don't have to be scared the tiles get pushed around.

I added aditional beams, because I found that printing the big ones without them gives a very bad texture at the bottom. And if I put the time and money in tiles, I want them to be pretty and sturdy.

Instructions:

• Print the tiles of your choice.
• Remove the small supporting pins on the sides.
• Print Openlock clips to connect the tiles.
• Push one or more Openlock clips into the tiles (depending on the size of the tile 1 can be enough, 2 works best with big tiles).
• Connect the tiles together.
