Yeelight dimmer dry lining back box

Slightly modified from Aqara box: https://www.thingiverse.com/thing:3000987

Modifications:
Dimmer fitment to box
Back panel fitment (press-fits together)
Tighter screw holes (you can now use screws included with yeelight dimmer)

M3x55 screws (or longer) and M3 nylon locknuts are needed for assembly.

Highly recommend to cover inside of the box with fire stop putty pad, for example: https://www.hilti.co.uk/c/CLS_FIRESTOP_PROTECTION_7131/CLS_FIRESTOP_PUTTIES_7131/r4673
This protects the box and construction from potential fire and restores wall acoustical performance.

Print instructions

Prints great with Prusament PETG with following settings:
0.4mm nozzle
0.2mm layer height
25% infill
Avoid crossing perimeters (I'm using Prusa mini, might not be needed with direct-drive extruders).

PLA will also print fine, but has lower melting temperature and is therefore not recommended.
Can't print in ASA. I've tried multiple times even with a raft but object starts warping badly at 15-20mm height.
