A way to hide Ethernet (or any other cable) behind dry wall. This is for a 25mm hole saw & can be adjusted by changing the value of OD. Note that OD is the diameter without the size screw thread.
Ver 05: Wider gap between threads for harder drywall

Note: the version with a catch is single use - you will need a side cutter to take it apart once the catch has engaged.
