Radiator Valve Cap

This is a replacement Radiator Valve Cap for a 12mm hex insert and an M5 bolt used to turn each isolation valve on or off.My original cap broke after many years of use and i could not find an STL for my radiator so i made one.The hexagonal insert of the original cap and the M5 bolt are both required for proper interfacing.
