Pass-through Wall Box for Ethernet Coax Wiring Panels etc

thingiverse

This in-wall wall box is for adding a low-voltage wiring panel when the drywall is already in place and you need to cut (see cutout size under "Usage"). All of the concave corners are rounded for strength. There are x-shaped support ridges on all 4 sides on the inside for additional strength. ## License - [Creative Commons - Attribution](https://creativecommons.org/licenses/by/4.0/) (CC BY 4.0) - by Poikilos.org https://www.thingiverse.com/poikilos [support me](https://flattr.com/@Poikilos) ## Usage Print after the first 3 steps, not before. Proceed at your own risk. 1. Where you want your low-voltage wall panel, safely ensure no electrical wiring is behind the wall, such as using a stud finder with electricity detection and with something running on the outlets to ensure power is detectable (I'm not sure if any/all stud finders require that in order to detect wiring). - Ensure that this device will not make your wiring fail building code in your area. 2. Pick a place where there is a stud exactly on the edge of where your hole will be if you want the stopper feature (see Step 5). 3. Cut a hole 2 x 3.75 inches in the wall on both sides (Drilling with a long bit after cutting one side can help you align the two cutouts, and doing so after making the first cutout is safer since you'll see what is behind the wall). 4. Check the distance between the outside of one wall and the outside of the other, and change the model if it differs from this model (which assumes 4.5"). 5. Check the thickness of the drywall on the side you want to use. The model has (3) 1/2" deep stoppers (1/16" case you have picked a place that has a stud. The stopper will ensure that the box doesn't fall into the wall, but only if the box is up against a stud. 6. The size is ensured to be correct, print the part and insert it into the cutout you made in the wall.
