Audi A3 8P 3D Models: STL Interior Parts

This collection gathers 3D printing files made for the Audi A3 8P generation, from cup holder inserts and phone mounts to keychains and small trim clips. Most of them are compact parts that fit inside the cabin, so they are practical subjects for a desktop 3D printer. Browse the list to see which STL files match the part you are missing or want to replace. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Audi A3 8P 3D Models: STL Interior Parts»

The models fall into a few clear groups. Storage inserts replace or extend the cup and coin holders, while phone mounts attach around the dashboard, vent or centre console. Keychains and small badges are decorative and quick to print, and a separate group covers clips, latches and fasteners that hold trim or the parcel shelf in place. A few interior add-ons, such as gauge housings or shift paddles, sit closer to the dashboard and steering wheel.

Before printing, open the author's page and read what is listed there: the dimensions and scale, how many separate parts the model has, whether it is split for assembly, and whether supports are needed. The material and settings the author names matter for parts that sit in a hot car, since some plastics soften faster than others. Look at photos of real prints to judge wall thickness, tolerances and how the part meets the original trim.

To widen the search, try the chassis codes that appear alongside the model name, such as 8P and 8PA, and related terms like S3 or RS3 for the same era. Useful synonyms include cup holder insert, coin tray, phone cradle, vent mount, key fob, trim clip and parcel shelf fastener. Adding the year range or the body style can narrow results further, and swapping between "mount" and "holder" usually returns different sets of files.

FAQ

よくある質問

What does 8P mean in these model names?
It is the internal chassis code for one generation of the Audi A3. Parts made for 8P bodies generally do not fit later generations such as 8V or 8Y, so check the code before downloading.
Do these interior parts need supports?
It depends on the shape. Flat inserts often print without them, while mounts with overhangs or screw bosses may need them. The author's page usually states what was used.
Which material is used for parts that stay in a car?
Authors often list PETG, ABS or ASA for interior parts because they tolerate heat better than basic PLA. Check the material and settings noted on the model page and compare them with what your printer can handle.
Can I resize a keychain or badge?
Yes, these are usually simple shapes that scale in the slicer. Adjust the size to the keyring or surface you have, and recheck the hole diameter after scaling.
