Hyundai i30 N PDE speaker rings e.g Audison AP 6.5

Hyundai i30N Speaker adaptor for the Audison AP6.5 Speakers.

Since the inside of a car door can be pretty hot, don't use PLA!
I used PETG and it works fine. ABS or ASA may even be better.
You may need to sand a small groove in the bottom for the cables going through - I might update this in further iterations.

The white ring was my first iteration with PLA to test if everything fits fine.
