Car Phone Holder 3D Models and STL Files

This collection covers 3D models of phone holders meant to sit in a car: gravity grips, vent clips, ball-mount arms and adjustable brackets. The files differ in how they attach, how many parts they use and how much of the phone they cover. It is a useful starting point for 3D printing a holder around your own dashboard, vent or phone size. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Car Phone Holder 3D Models and STL Files»

The models fall into a few families. Gravity holders use the weight of the phone to close two arms, so they have few moving parts and no spring. Vent mounts clip onto an air vent and are usually the smallest option, while ball-mount and modular designs separate the attachment from the cradle, so the same arm can carry different holders. Adjustable and gear-driven versions add a hinge or a rack so the angle can be changed after assembly.

When you pick a model, read the author's page rather than the preview image. Check the listed phone size range, the number of printed parts and how they join, whether screws, springs or magnets are needed, and whether the author shows supports in the orientation they used. Look at photos of real prints to judge wall thickness and how the clip meets the vent or dashboard. For material, remember that a car interior gets hot in the sun, so many makers list PETG, ABS or ASA instead of PLA, along with their layer height and infill.

If the results feel narrow, try other wording. "Phone mount", "phone cradle", "smartphone bracket" and "car dock" describe the same object, and "gravity grip" or "vent clip" narrow it to one mechanism. Related searches include dashboard mounts, CD-slot holders, ball-joint arms and magnetic plates. You can also search by the part you want to reuse, such as a specific ball diameter or a clamp that matches a bike or desk mount.

FAQ

Frequently asked questions

What material should a car phone holder be printed in?
Because a parked car can get very warm, PLA may soften in summer. Many authors list PETG, ABS or ASA and give their own temperature and strength reasoning, so check the model page before choosing.
Do these holders need supports?
It depends on the orientation. Arms, clips and curved cradles often have overhangs, while flat-backed designs can print without them. The author's page usually shows the orientation and whether supports were used.
How do I know a holder will grip my phone?
Look for the phone width or thickness range the author lists, and compare it with your device, including its case. If the model is parametric or offered in several sizes, pick the one closest to your measurements.
How does a gravity phone holder work?
The phone's weight pushes a lower support down, and that movement pulls the side arms inward to hold the device. It needs no spring, but the sliding parts must be printed cleanly to move freely.
