keystone wall box

The 3 part design makes for an easy assembly and a clean look without visible screws.

I also designed a version to fit two jacks. However I did not need one yet and haven't bothered printing it. You will need the mirrored frame for the double box.

Update 2026-06-04:
Added new frames with looser tolerances (see file names and descriptions) as some report issues with the originals being too tight to comfortably fit or be disassembled. I haven't tested these looser frames, as mine worked alright and I usually like the tolerances to be as small as possible making the assembly feel nice and solid.
