Nothing Phone 3 Cover: 3D Models and STL Files

This collection gathers 3D models for phone covers, cases and related accessories, from Nothing and CMF shells to flexible cases for other brands. Files are grouped by phone model and by design approach, so you can compare shapes before opening a slicer. It is a starting point for anyone who wants a custom shell instead of a shop-bought one and prints it on a 3D printer. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Nothing Phone 3 Cover: 3D Models and STL Files»

The range splits into a few clear groups. Rigid back covers and bumpers appear for Nothing and CMF phones, while soft TPU-style cases dominate listings for iPhone sizes. There are also modular designs with swappable inserts, covers for older handsets such as Nokia, Pixel, Galaxy and OnePlus models, and simple stands or holders that sit next to a case in the same search.

When you open a model page, check the wall thickness, the cutouts around buttons, ports and cameras, and whether the shell is one piece or several. Look at the size and scale the author states, since a cover drawn for one screen size will not fit another. Read the material and settings the author lists, note whether supports are needed for overhangs, and study photos of real prints to judge how the surface and corners come out.

Searching is easier with synonyms. Try case, shell, bumper, back cover or housing alongside the phone name, and add the model generation if you know it. Related topics that often lead to useful files include modular inserts, camera bump guards, stands, holders, and printable accessories that clip onto a phone.

FAQ

Questions fréquentes

What file formats do these phone cover models usually come in?
Most listings provide STL, and some authors also include STEP or 3MF files. The format matters if you want to edit the shape before slicing.
How do I pick a cover for the right phone generation?
Compare the dimensions the author gives with your handset, and check the camera and button cutouts. Covers for a similar model from the same line often differ in size.
Do phone covers need supports?
It depends on the design. Flat back covers often print without them, while shells with deep cutouts or overhangs may need them. The author's notes usually say which case applies.
Which material works for a thin phone shell?
Authors commonly list TPU or another flexible filament for snap-on cases and PETG or PLA for rigid covers. Follow the settings on the model page rather than guessing.
