Sonoff POW Elite with UK (Type 86) Power Box

This model was made to hold a POW Elite and a single-gang UK power box. You can utilise that single-gang box as either an intake power switch (to cut power to the POW Elite, and therefore its downstream devices), or a power socket as the downstream device of the POW elite.

The proper rated type 86 power box will allow you the sturdiness and security rather than 3d-printed layers for something that might hold some level of heft and cable weight.

The 1cm hole at the bottom allows for a shielded 3-strand cable to ingress.

All screw holes are meant for M3 inserts, except for the one holding the POW Elite, where its DIN rail holder has a large screw hole where an M3 screw wouldn't be suitable, but I left a 2mm hole to ensure the mount is aligned.

Holes for the type 86 power box are spaced 1.7cm from the edges, which is the measurement of my power box's mounting holes bought from a hardware store.

(Note that the images shown are cut at a z-height for a test fit of the prototype; the uploaded model has displaced the POW Elite's mounting bar lower by 11mm and shorter by 1mm such that it will fit snugly in the box with a good 2-3cm of clearance at the bottom for the cables to run).
