The Hardboard or Clear Plastic Box Corner.
I made this because I needed to make a box to protect my 3d printer from sawdust in my workshop.
Print 8 of these and with some 3/16" hardboard or clear plastic from your local home center, you can build a 5 sided box. These corners build the 4 walls and you can lay a panel on top to "close" the box.
Edit: Added another corner design. This one has two 1/4 inch holes so a Clevis Pin (1 3/4") and R-clip can be used to secure the boards in place.
