This is a wall charger for an Apple Watch, build around this Charger:

The charger is sold on Amazon under several brands, the dimensions of my charger are approx. 24,35mm with, 69mm length.
The model is heavily inspired by this great model from Sepp. I only had a very old original apple charger with USB-A and without quick charge capabilities, so i remixed it.

The Model needs to be printed with supports to support the part which goes into the socket.
I printed it in PLA and in ABS, both works fine.
The author remixed this model.
