screw clamp case

This is a small case to minimize the risk of comming into direct contact with live wires connected by terminal block.

The cross in the middle will grib onto the clamp.
The entry and exit holes for the cables are only for flat cables and it's slightly narrower in order to hold the cable firmly in placebit titer than the cable to hold it at place.
