Tag along on my journey of modding a 2.1″ IPS display into a custom-3D printed air vent to display ODBII info wirelessly from the car. I’ll be doing a series of videos as I model and print the vent + mounting components, build and program the display and features, then install and fit in the Miata. Be sure to subscribe here and on my YouTube channel (below) to get notified.

From a parts perspective, this is a relatively simple build. We have a plug-and-play ODBII reader, a microcontroller that needs only power (communicates to the reader via Bluetooth), an IPS display and a 3D printed vent system. The heavy lifting is in getting the display and ESP32 to talk and modelling/printing a vent that fits and is still functional.

I’ll post new videos and updates here as this project progresses. Subscribe to my YouTube channel to get updates.
