Holds two pieces of cardboard together.
We have two boxes that, when put on top of each other, is a great hiding place for the cats. However, they keep knocking the top one down. I made this piece to hold them together. The bottom box edge is thicker, as it is made of several pieces of cardboard.
For the perpindicular, the two edges have the same thickness.
If you want to stick together two single pieces of cardboard, edit the .scad file so both sides have the same thickness as the top one has now.
On the perpindicular, both sides fit a single piece of carboard.
