Switch is intended to have 230V 6A load and 125v 10A load but this enclosure is not intended to be used with main power. Doing it you may violate local electrician code!
Designed to be used in the van switching 12V 5-10A only. Other options on your own risk.
Use PETG 100% infill, no supports needed, some stringing or slightly collapsed bridging may appear from inside but not really important as not visible. Use pair of wood screws to secure halves together - at least 20mm x 3mm size, good to heat them with soldering iron to melt thread in.
