Universal Nest Protect V2 Junction box

This is an universal junction box for the Nest Protect V2.
It was designed to mount a mains powered NP anywhere on the ceiling / wall and provide room for the cabling and connect to cable ducts.
There are two entry / exits points with strain reliefs with breakout hole covers, which allow end or feedthrough cabling.
There are 4 screw holes that allow the unit to be mounted with the original NP screws.
However I used carpet sticky tape to fix the unit onto my ceiling

I used the following materials:
4x 3.5 x 20 mm woodscrew to mount the mounting bracket
2x 3.5 x 16 mm woodscrew to mount the strain relief
1x 2 pole 1.5-2.5mm2 screw connector

Notes:
- Breaking away the hole covers requires a bit more force than intended, but suggest to remove from the inside out.
- Do not fully tighten the screws of the mount plate as it will compress the rubber ring fully and will not provide room to slide the NP on
