Mark 4 5-Inch FPV Frame 3D Models and STL Mounts

This collection gathers 3D models tied to Mark 4-style 5-inch FPV frames, from full frame plates to camera, air unit and antenna mounts. It is useful when you are building or repairing a quad and need STL parts that match a specific frame layout. Most files here are small brackets rather than whole aircraft, so 3D printing them is a quick way to adapt a frame you already have. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Mark 4 5-Inch FPV Frame 3D Models and STL Mounts»

The largest group covers 5-inch quad frames and the parts that bolt onto them: camera mounts for GoPro-style action cameras, holders for DJI O4 and O3 air units, antenna brackets and connector plates. A smaller group comes from scale modeling, where frames of front-engine race cars are printed as display pieces. The two groups differ in purpose — one is functional and load-bearing, the other is decorative and judged by surface detail.

When choosing a file, read the author's page before printing. Check the stated dimensions and scale, the number of separate parts and how they join, whether supports are needed, and which material and settings the author lists. For camera and antenna mounts, look at the mounting pattern, hole spacing and wall thickness, since these decide how the part behaves on a vibrating frame. Photos of real prints are more informative than renders.

To widen the search, try related terms such as quadcopter frame, camera mount, air unit bracket, antenna holder or TPU mount, and add the frame size or camera family you are working with. If you are after display models instead of flying parts, search for scale model frame or race car frame. Combining a part type with a frame style usually narrows results faster than a single broad word.

FAQ

Perguntas frequentes

What is a Mark 4 5-inch frame in FPV terms?
It is a frame layout for 5-inch propeller quadcopters, and the Mark 4 naming is used across several versions and clones. The exact plate shapes, hole positions and camera cage differ between them, so check the drawing on the author's page.
Which material works for camera and antenna mounts?
Flexible filaments such as TPU are commonly used for mounts that absorb vibration, while rigid filaments are used for brackets that must hold shape. The author's page usually states the material and settings they used.
Do these parts need supports?
It depends on the geometry: flat brackets often print without them, while angled camera cages may need supports under overhangs. The model page or the slicer preview shows where supports would be required.
How do I find a mount for a specific camera or air unit?
Search by the camera or air unit family plus the part type, for example a mount name together with the frame size. Then compare the mounting hole spacing and overall height with your own hardware.
