iPhone 8 3D Models: STL Cases and Holders

This collection gathers STL files for iPhone 8 cases and the accessories designed to hold a cased phone. It covers flexible shells, patterned bodies, camera protection and dock-style parts, so you can compare approaches before committing to a print. Most entries are small, single-piece prints that fit a standard 3D printer bed. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«iPhone 8 3D Models: STL Cases and Holders»

The models fall into a few groups. Flexible shells are thin-walled and meant for a soft filament, while rigid patterned bodies use hexagons, voronoi cells or similar cutouts to reduce material and add grip. A third group adds functional details such as a raised camera guard, cooling holes or a logo recess. Docks, stands and wall holders are a separate family: they are shaped around the outer dimensions of a cased phone rather than the bare device.

Before printing, open the author's page and read what is listed there. Check the stated size and scale, the number of parts and how they join, whether the model needs supports, and the material and settings the author names. Look at photos of real prints to judge wall thickness, camera cutout alignment and how the sides flex. If the model is a dock or holder, confirm the inner opening matches the case you actually use, since a shell adds thickness.

To widen the results, try other words for the same object: bumper, shell, cover, protective case, or the material names TPU and flexible filament. Accessory searches work better with terms like dock, stand, wall mount or charging station. Many designs are shared across neighbouring generations, so searching for iPhone 7, SE or 6 alongside iPhone 8 often surfaces the same geometry with a different label. Combining a case term with a feature word such as camera guard, hexagon or voronoi narrows the list quickly.

FAQ

Häufige Fragen

Which filament works for a phone case?
Flexible shells are usually printed in TPU or a similar soft filament so they can be stretched over the phone. Rigid patterned cases are commonly printed in PLA or PETG. The author's page usually names the material the design was made for.
Do these cases need supports?
It depends on the model. Flat-backed shells with a simple camera opening often print without them, while designs with overhangs, recessed logos or dock geometry may need supports. Check the print notes on the model page.
Can a case for iPhone 7 fit an iPhone 8?
The two devices share very similar outer dimensions, so many designs are published for both. Button and camera positions can still differ slightly, so compare the author's stated dimensions with your phone before printing.
What should I check before printing a dock or holder?
Measure the outer size of your phone with the case on, then compare it with the opening the author lists. Also check how the part is mounted, whether it is screwed, glued or clamped, and how much clearance the connector area has.
