UK plug ground pin replacement adaptor

ONLY USE ON PLUGS WITH A PLASTIC GROUND PIN NOT METAL ( where they use the plastic ground pin as a key to slide open the port for the other 2 live and neutral pins and not as an actual ground ).

I accidentally dropped my expensive 100W USB C charger and broke the plastic ground pin off so this is a 3d printed replacement i glued on.

2 files are attached, one fully printed and one that takes a 3x20mm screw directly droven into the 3mm wide hole in the pin, taking advantage of 3d printing tolerances to provide friction. This reinforces the pin and should be safe (?) given that its insulated by the surrounding plastic.
