Network Cable Drywall Passthrough

Instructions:

- Drill a 20 mm hole through the wall
- Choose the "long" part according to the thickness of your wall
- Insert the "short" part on one side, and the long part on the other
- Fasten with a 3 mm wood screw that's long enough to reach the other part
- Push the cable/cables through.
- Install the lid for one or two cables. You might want to bend the lid slightly while installing as the snap fit clips break easily

Notes:
- I've only used PETG for this, so I can't comment on the performance of other materials.
- Some cables have big connectors that might not fit through, see image
- I've managed to cram up to three cables through, but I don't have a lid for this.
