Switch mount in duplex outlet form factor

This is admittedly a very niche item, but since I search for something like it before I made one myself, maybe someone else will find it useful.
I have a 6' industrial workbench, and the risers for the upper shelf have knockouts for mounting duplex electrical outlets. I wanted a place to mount the switches that would control the LED lighting strips so I designed this piece to fit on one of the outlet spots. It is designed to hold 2 round-bodied rocker switches, model KCD1-5 from DaierTek.

I printed it at 0.2mm layer height, no supports are necessary, and secured it with some #6 machine screws.

Update August 2021: Added the step file in case anyone wanted to modify it for another purpose.
