I made this adapter because my original speakers didn't work, I replace them but needed a universal adapter for my Opel Astra H from 2006, so this model was the solution.This model fits perfectly in my car, you can buy any speaker with a 130mm diameter, and then you just need to buy an adapter cable from the speaker to your car.

Print Tips*

• Layer Height: 0.2mm;
• Infill: 20%;
• Supports: No;

• These are my recommendations for the same result then you can see in the pictures, but you can change the settings to fit your needs.

Good Luck,ProMelt.
