I was looking for a way to make a frame using 2020 aluminum extrusoin. I wanted to have the inside track corners to be open to accept a plexiglass sheet. I searched for a connector, but only found a 3-way corner connector, or a cube connector, so I decided to design a 2-way connector.

Notes:

The connection is designed to be snug to keep parts together. I used a clamp to press joint together.
Despite the snug fit, I found the single prong was still too loose, so I added the two holes in the single prong connector. The holes are designed with a countersink to use with a M3x4 cap head screw.
