A mounting system for the Powerwerx Four Hole Square Panel Mounting Plate

https://powerwerx.com/four-hole-square-panel-mounting-plate

For my purposes, the brim around this mounting panel just wouldn't be sufficient for a lean mount.  There's just not enough space between the screw holes and the edge.

This mounting systems lets you mount the panel in a larger, rectangular hole, and the whole thing is held in place by the clamping pressure of the screws holding the whole thing together.

I've printed the whole thing in PETG, but I've not yet installed it.  I will add new photos when I do.

I've included a BLANK front panel, as well as the one with “12V 40A” engraved.

NOTE:  The dimensional diagram from Powerwerx was NOT ACCURATE for me.  The spacing of the screw holes was a bit different.
