For those of you who want the LED light bar and switch https://www.thingiverse.com/thing:3292889 but don't need the whole front SD card converter and housing https://www.thingiverse.com/thing:3292867, here is my simple box for holding the switch and electrical connectors.

You can screw to your aluminum extrusions with m4 screws and T nuts. There is a rear cap to close off the back if needed.

I recommend bolting on to your frame first, passing the cabling in through the rear and out the front hole, wiring the to the switch, then snap the switch into place
