Part 2: 3D printing

A project log for Tesla Key Watch

Embedding a J3A040-CL chip and a custom antenna into a modified Casio F-91W for accessing my Tesla Model 3.

First thing I designed was the new F-91W chassis

Obviously it took me a few tries to make the new chassis fit properly.

Well... maybe more than "a few".

This process was made way easier thanks to N-O-D-E sharing his project files.

Then, to make my life easier, I started printing a few instruments for building the antenna. The first thing I designed was a guide for the wire to be wrapped around.

Then I needed a loop antenna for my NanoVNA for the antenna matching stage.
