this is a template piece to fit onto the end of a broken Tesla mobile charger. I have included the template piece and the STL piece that I used to repair mine.
The use of “J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe - Black - 25 ml” allows for the piece to be combined with the broken charging leads that does not conduct any electricity. It allows to fill voids and it easy to sand.
