I found this adapter on thingiverse and I love being able to grab my charging adapter quickly and easily right inside the driver’s side of the trunk. Plus, it required no drilling or modifications to my model Y as that triangular opening already existed. However, I wasn’t pleased with the print quality with the combined model so I broke it into two parts for cleaner printing.
I printed mine in ABS but ASA would work as well. Not sure how the hot temperatures in the car would affect PETG but you could always try.
The two parts are held together with pan head wood screws. The center hole accommodates a #7 x ½” and is the main support. The other two smaller outside screws are #4 x ½” and prevent rotation of the holder.
The author remixed this model.
I made the mount and the clip separate for easier and cleaner printing. It also allows for easier repair in the event one of the parts gets damaged.
