Credit to Forest Katsch for this model.
Fits into the Model 3/Y center console wireless charging pads and holds AirPods Pro in exactly the right spot to charge wirelessly.
Given the extreme environment in a vehicle, high-temperature filament such as PETG is very strongly recommended (a test print in PLA warped beyond a usable shape within days.)
The original CAD model at OnShape is included here, so you can remix to your heart's content. I've built an untested and unprinted configuration that should work with Nomad's AirPods Pro case based off their website specifications, but I have not printed or tested this yet.
