Designing Custom FPV Camera Mounts with Fusion 360: A Complete Tutorial

Designing Custom FPV Camera Mounts with Fusion 360: A Complete Tutorial

Off-the-shelf camera mounts often fall short when you’re building a custom FPV drone. The camera angle might be wrong, the mounting holes might not align with your frame, or you might need to accommodate an unusual camera-VTX combination. Learning to design your own 3D-printed camera mounts in Fusion 360 unlocks unlimited customization — and it’s easier than you might think. This step-by-step tutorial walks through the entire process of designing a professional FPV camera mount, from initial measurements to print-ready STL file.

Why Fusion 360 for Drone Parts?

Fusion 360 is the standard CAD tool for FPV drone part design, and for good reason. Autodesk offers a free license for hobbyists and makers (renewable annually), the parametric modeling workflow makes iterative design changes trivial, and the integrated CAM and rendering tools are useful for advanced projects. While alternatives like Onshape (browser-based) and FreeCAD (open-source) exist, Fusion 360’s combination of capability, community support, and tutorials make it the best choice for drone parts design in 2026.

Before You Begin: Measurements and Reference

Good design starts with accurate measurements. Before opening Fusion 360, gather:

  • Camera dimensions: Width, height, depth, and lens diameter. Measure with digital calipers — guessing leads to parts that don’t fit.
  • Frame mounting pattern: The distance between the mounting holes on your frame, the hole diameter (typically M2 or M3), and the standoff height.
  • Target camera angle: Typical ranges are 20-30° for racing, 30-45° for freestyle, and 15-25° for cinematic flying. Your mount should either be fixed at your preferred angle or adjustable within a range.
  • Clearance requirements: The camera must clear the frame’s top plate, the stack electronics, and the propeller arc. Measure the available space with the frame assembled.

Step 1: Create a New Design and Set Up Parameters

Open Fusion 360 and create a new design. The first and most important step is defining parameters — named variables that control your design’s dimensions. Parameters make your design adaptable: change one number and the entire model updates automatically.

In the Modify menu, select “Change Parameters” and create these parameters:

Parameter NameValueDescription
cam_width19.0mmCamera body width (e.g., Caddx Ant)
cam_height19.0mmCamera body height
cam_depth18.0mmCamera body depth
lens_dia14.0mmLens housing diameter
frame_width30.5mmFrame standoff spacing
mount_hole_dia3.2mmMounting hole clearance for M3
cam_angle35degFixed camera angle
wall_thickness2.5mmWall thickness for 95A TPU

Step 2: Create the Base Plate

Create a new sketch on the XY plane. Draw a rectangle centered on the origin with dimensions frame_width × cam_depth + 10mm (extra length for structural integrity). Extrude this to wall_thickness (typically 2.5-3mm for TPU). This is your base plate.

On this base plate, create mounting holes. Draw two circles at (±frame_width/2, 0) with diameter mount_hole_dia. These align with your frame’s standoffs. For frames with 20×20 or 30.5×30.5 mounting patterns, adjust the hole positions accordingly. Consider adding slots rather than holes for variable position adjustment — an 8mm slot provides ±4mm of positional adjustment.

Step 3: Create the Camera Cradle (Side Plates)

Create a new sketch on the XZ plane. Draw the side profile of your camera mount. Start from the base plate top surface and draw upward to create one side plate. The side plate should be at least 10mm taller than your camera height to provide secure retention. Add a curved cutout at the front for the lens barrel.

Extrude this side profile symmetrically to create two side plates spaced cam_width + 0.5mm apart. The 0.5mm extra width ensures the camera fits without excessive force while maintaining a secure friction grip — TPU’s compliance makes this tolerance forgiving.

Step 4: Add Camera Angle Features

For a fixed-angle mount, create the side plate geometry so the camera sits at your target angle relative to the horizontal base. Draw a construction line at your cam_angle from horizontal, then align the camera retention features to this angle line.

For an adjustable mount, create pivot holes on each side plate at the camera’s center of rotation and an arc slot for the adjustment screw. The pivot and slot should form a circular path centered at the pivot point with a radius equal to the distance between the camera’s mounting screws. Add angle markings (laser-etched or printed) so you can set angles consistently in the field.

Step 5: Add Retention Features

The camera must stay in place during crashes and aggressive maneuvers. Add these retention features:

  • Friction ribs: Small vertical ridges (0.5mm tall, 1mm spacing) on the inside surfaces of the side plates. These compress against the camera body and prevent sliding.
  • Top retention tab: A flexible tab that snaps over the top of the camera. Design it as a cantilever beam 8-10mm wide, 2mm thick, extending from the back of the mount. TPU’s flexibility allows the tab to bend during insertion and spring back into place.
  • Screw retention: For M2 camera mounting screws, design clearance holes (2.2mm diameter) in the side plates at positions matching your camera’s mounting points.
  • Lens barrel support: Add a U-shaped cutout at the front of the mount that partially surrounds the lens barrel. This stabilizes the camera against forward impacts and prevents the lens from taking direct hits.

Step 6: Add Structural Reinforcements

3D-printed parts are weakest along layer lines. Add these reinforcements to prevent delamination:

  • Fillets: Apply 2-3mm fillets to all internal corners where the side plates meet the base. Sharp corners concentrate stress and are crack initiation points.
  • Gussets: Add triangular gussets at the base of tall vertical features. In Fusion 360, use the Rib tool to automatically generate gussets.
  • Chamfered edges: Chamfer the outer edges of the base plate to reduce peeling during printing and improve durability.

Step 7: Export for 3D Printing

Right-click the body in the browser and select “Save As Mesh.” Choose STL format, set refinement to High, and export. The STL is ready for your slicer.

Printing Considerations for Camera Mounts

Camera mounts demand specific print settings for optimal performance:

  • Material: 95A TPU is ideal. 98A or HD TPU for fixed-angle mounts that need more rigidity.
  • Orientation: Print with the base flat on the build plate and the side plates standing vertically. This orientation aligns layer lines perpendicular to crash forces, maximizing strength where it matters.
  • Support: Most camera mounts print without supports if designed with 45° overhangs or less. If supports are needed for lens cutouts, use organic/tree supports that are easy to remove from TPU.
  • Infill: 40-50% gyroid. The side plates experience compression and shear — gyroid infill provides uniform strength in all directions.
  • Walls: 4 perimeters minimum. The side plates are relatively thin and benefit from additional walls.

Testing and Iteration

Your first print won’t be perfect — that’s expected. Print a test piece, install the camera, and evaluate:

  • Does the camera fit securely without excessive force?
  • Are the frame mounting holes correctly aligned?
  • Does the lens clear the frame and props at all angles?
  • Is the camera angle correct for your flying style?
  • Does the mount flex excessively during aggressive maneuvers?

Adjust your Fusion 360 parameters based on test results, re-export, and re-print. The parametric design makes iteration fast — changing cam_width from 19.0 to 19.5mm takes seconds and updates the entire model. A well-designed mount typically requires 2-3 iterations to perfect.

Advanced Techniques

Once you’ve mastered basic mounts, explore these advanced features:

  • TPU vibration isolation: Design the mount with thin, flexible connecting sections (1.5mm) between the camera cradle and the frame mounting points. This creates a mechanical low-pass filter that reduces jello in HD footage.
  • Integrated ND filter holder: Add a slot in front of the lens for drop-in ND filters — critical for cinematic flying in bright conditions.
  • Dual camera mounts: Mount an FPV camera and an HD recording camera in a single TPU cradle, with the lenses aligned to the same angle.
  • Breakaway design: Design deliberate weak points (1mm necks) that break in severe crashes, sacrificing the mount to save the camera and frame.

Custom camera mounts are the gateway drug to drone CAD design. Start with this tutorial, iterate on your own designs, and soon you’ll be modeling entire frames. Fusion 360 is a deep tool, but 80% of what you need for drone parts can be learned in a weekend. Happy designing!
