Deta TTE Trunking (2-way) Junction wiring box

I am using some white PVC trunking to tidy some wires, and I wanted a junction box which could fit the following trunking: 

Deta TTE uPVC White Self-Adhesive Mini Trunking 25mm x 16mm x 2m

The junction box is designed to hold a RF433 wireless receiver like this one I bought from AliExpress.

The receiver is intended to be placed in line with the light (or load) you want to switch on an off. The junction box therefore only has two entries (one on each side). The enclosure is designed so that it perfectly fits this receiver.

Assembly

I made the print to pause at height twice to insert two M3 hexagonal nuts at each corner. The screw holes go all the way through the enclosure so any screw can be accepted. The enclosure lid has sunken holes so that socket cap head screws sit flush with the surface.

The trunking has a loose friction fit, it doesn't need to be tight for this trunking. The trunking slots into the shrouded recesses perfectly, so no gaps are shown.

Notes:

I did not upload “version 1” of this project because I felt it was an inferior model, but I kept the revision levels (for my benefit). The FreeCAD model is attached so you may make your own modifications to the model.
