Cable Junction Box Relay Inset

This is a very specific inset for a cable junction box. I was looking for some robust industrial and cheap box to build a remote power switch by inserting a relay module into the box.

I found and ordered [this box](https://www.aliexpress.com/item/1005005709986125.html) on ali express (3 way waterproof wire junction boxes).

The box is suitable to fit a relay module of [this type](https://www.aliexpress.com/item/1005004920370698.html).

In order to perfectly fit the relay module as well as providing some cable guidance I created this inset. It perfectly fits into the 3-way box. The relay just need to be clipped on. The inset also featuring 2 channels to route the cables underneath. The control cables (I used an old USB cable) can fit into one channel and the cables can be affixed by cable ties into the slots built-in to the model. So puling on the cable won't pull on the connectors.

Sorry for the bad pictures. As it is a prototype build I don't believe many people will need it
