The camera comes apart easily
The cable has to be cut free from the back of the

Three short hexagonal spacers and three small nuts
and bolts are needed
The project box is drilled for the bolts and the spacers
to hold the circuit board in place.
The drill bit passes through the circuit board and
drills through the appropriate spot on the front of the box.
Each bolt and spacer is put in place as each hole
A slot is cut through which the cable can pass
