This is a quick adapter to take an existing Anderson PowerPole connector design (https://www.thingiverse.com/thing:2965429), and make it fit on a single gang electrical box cover. I'll later modify it so it's all one piece.
This will allow me to put Anderson connectors in our motorhome, using standard electrical box type hardware.
The Fusion 360 file is included in case someone would like to tweak the design.
I used a #27 (0.144") to clean up all the holes to accept 6-32 mounting hardware.
