Adapter plate to mount the 180° reverse camera on a DS4 witch use a 130° as standard.
Print with ABS as PLA may be limited regarding high temperature

The camera is glued to the adapter plate.
The original mount (OEM) use two M2.5 screws, so you need to M2.5 inserts (In my case I used M2 with new screws because I did not have the M2.5 inserts)

For electrical connection and activation read this post on forum Peugeot:
