Hang cool stuff on your wall, in a hexagon-shaped box. I put preserved moss in mine. You can put other stuff if you want, though!

Comes in 3 sizes. For the largest size, you have to print in pieces and weld together. I coated it in plasti-dip to get the smooth borderless piece you see in the image.

Put mounting screws 8" apart to get the spacing effect shown in the image. Work from top to bottom. You can also use double-sided tape if you aren't putting anything heavy inside.
