Tesla A23 Battery Holder

In the rare case your Tesla 12v battery dies and you are locked out of your car (and hence cannot jump it), you can use a 12v battery or an A23 battery to pop the frunk using wires stored in the tow hook area in the front of the car.

This thing allows you to store the A23 battery in a relatively weather-proof container (with screw-on cap) attached securely to the frunk jumper wires and hidden behind the tow hook cover.

I printed this with PLA (better options are available) with 100% infill for strength. I used electrical tape to secure the vial to the wires after they were threaded through the wire holders. I then fed a zip tie around the wires and through the loop for extra security.

If needed, it would be very simple to unscrew the vial, while it is attached, and use the battery.
