Description
Corners that use 1/16" x 1" angle aluminum (commonly available from Lowes/Home Depot) at a lower cost than 2020 aluminum. The inner hole can be used to attach the angle bracket to the bottom surface (I used MDF) or to attach plexiglass/hardboard sides.
Holes are sized for M4 screws. You will need to cut the angle aluminum side to you desired length and drill the holes in the aluminum.
