Based on https://www.printables.com/de/model/235388-busch-jaeger-switch-cover/files

Needed an adapter that a.) covers the switch underneath and b.) could house a Sonoff SNZB-01 that controls some kitchen lamps via Home Assistant. So I came up with this, based on the file mentioned before. Printed in Basic White PLA, smooth build plate, tree supports and done in 25ish minutes. Sits very tight but I didnt want to use CA glue or anything else so this is intentional.
