Wago junction wiring box made for Deta TTE Trunking (3-way)

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 accommodates Wago 221-613 terminals, and a cable diameter up to 10mm in diameter. Inside the wire can be secured with a zip tie at the entry points. The Wago terminals are a tight friction fit which is quite strong. However, a small drop of CA glue or hot glue is recommended to permanently secure them.

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. Hence I uploaded this better one. The FreeCAD model is attached so you may make your own modifications to the model.
