Netatmo Relay - Cable mounting bracket

Netatmo relay bracket for the cable accessory.
When installing this relay close to a gas boiler, it is puzzling how unsuitable the factory design is for attaching it to any surface.

I have designed the rear part of it, to cover the mounting plug and leave room for wire tube around the cables.

There is also a zip-tie channel that allows attaching it without any double-sided tape.

PLA, no support needed, 15-20% infill is fine. Dimensions are perfect, do not scale it.
