PoE Box v2

Single Gang electrical box for low-voltage uses.

**THIS IS NOT UL APPROVED OR CERTIFIED!**

* Added standard size cut-out in the base
* Added pre-cut screw holes
* Added supports around face plate screw mounts
* Narrowed the walls and base for faster printing with less plastic (should still be plenty strong).

Did not add cut-outs on sides on purpose. Add these as needed at the time you print the box in just the places and at just the sizes you need. Most cat6 will fit through a 6.5mm cylindrical opening.
