Decora Keystone Plate

thingiverse

The original was generally a good fit, but I wanted the exposed face to even-off more to the surface of the outdoor wall plate I was using. I also found the keystone connection was too small in back to snap in. I had to remove a fair amount of material with a hobby knife to get them to work for me, so I adjusted the size accordingly. (I don't know if this is a characteristic of my printer making inside dimensions a little small, or if the original part opening is just too small. Perhaps some of both.) Mod2 has it's face 3.7mm (approx) extended. Mod3 is 4.7mm.
