3D Printing Drone Parts — Frames, Mounts & Custom Components

The FPV drone community was one of the first to embrace desktop 3D printing, and for good reason. Drone pilots crash constantly — it is part of the learning process — and being able to print a replacement camera mount in 45 minutes instead of waiting two weeks for a shipped part is a genuine competitive advantage. Beyond replacement parts, 3D printing enables fully custom drone builds with frames, mounts, guards, and accessories tailored to specific flight configurations.

This guide covers what you can print, which materials to use, how to design parts that survive crashes, and the regulations you need to know before flying a custom-built drone.

What Drone Parts Can You 3D Print?

Not everything on a drone should be 3D printed, but a surprising number of components work well. Here is what the community regularly prints:

Camera Mounts

Camera mounts are the single most printed drone component. Whether you are mounting a tiny FPV camera like the RunCam Phoenix 2 or a full GoPro Hero for cinematic footage, 3D printed mounts offer perfect fit and vibration dampening when printed in TPU. Retailers like MyFPVStore and GetFPV sell pre-printed mounts, but many pilots prefer printing their own for exact tilt angles and camera compatibility.

Common camera mount types:

• FPV camera mounts — Hold small board cameras at adjustable tilt angles, typically 25-45 degrees for racing drones.
• GoPro and action camera mounts — Secure larger cameras with vibration dampening for smooth footage.
• Insta360 mounts — 360-degree camera mounts with invisible selfie stick positioning.
• DJI O3 Air Unit mounts — Custom housings for the DJI digital FPV system.

Antenna Mounts and Holders

Antenna positioning matters for signal quality. 3D printed antenna mounts hold video transmitter antennas, GPS antennas, and receiver antennas at optimal angles. TPU mounts flex on impact instead of snapping, protecting both the antenna and the frame.

Frame Components

While most racing drone frames use carbon fiber plates, the connecting structures, arm protectors, and motor soft mounts can be 3D printed. Some pilots print entire frames for lightweight camera drones and long-range cruisers where maximum speed is not the priority.

Pyrodrone offers an extensive collection of 3D printed TPU parts specifically designed for popular drone frames.

Protective Components

• Prop guards — Essential for indoor flying and proximity flights. TPU prop guards absorb impacts without shattering.
• Motor soft mounts — TPU dampeners between the motor and frame that reduce vibration transmitted to the flight controller.
• Landing gear — Flexible TPU legs that compress on hard landings.
• Battery pads — Non-slip TPU pads that keep LiPo batteries from shifting during aggressive maneuvers.
• Arm guards — Slide-on protectors that absorb crash damage before it reaches the carbon fiber arms.

Accessories

• Battery strap holders and guides
• Buzzer mounts
• LED strip holders for night flying
• Crossfire/ELRS receiver mounts
• Stack spacers and standoffs
• Turtle mode skids (protect cameras when the drone is inverted)

Material Selection — This Is Where It Matters Most

Choosing the right material for each drone component is critical. The wrong material turns a minor crash into a major rebuild.

TPU (Thermoplastic Polyurethane) — The Default Choice

TPU is the dominant material for 3D printed drone parts, and for good reason. It is flexible, impact-resistant, and returns to its original shape after deformation. As MakerVerse's drone printing guide explains, TPU absorbs crash energy instead of transferring it to other components.

Best for: Camera mounts, antenna holders, prop guards, motor soft mounts, landing gear, and any component that needs to survive impacts.

Print settings for TPU drone parts:

| Setting | Value | |---|---| | Nozzle Temperature | 220-235°C | | Bed Temperature | 50-60°C | | Print Speed | 20-30 mm/s | | Infill | 30-60% (higher for structural mounts) | | Infill Pattern | Gyroid | | Wall Count | 3-4 | | Retraction | Minimal or disabled | | Fan | 50-80% |

TPU shore hardness matters. Most drone TPU parts use 95A hardness, which balances flexibility with rigidity. Softer grades (85A) work for motor dampeners. Harder grades (98A) work for structural mounts that need less flex.

PETG — For Rigid Structural Parts

When you need rigidity but do not want the brittleness of PLA, PETG is the choice. It handles heat better than PLA (important in summer or near motors) and has better impact resistance.

Best for: Frame plates, electronics enclosures, mounting brackets, and any part that needs to stay rigid.

PLA — Only for Prototyping

PLA is too brittle and heat-sensitive for flight-ready drone parts. Use it for design verification — print a prototype to check fit, then reprint in TPU or PETG for the actual flight part.

Carbon Fiber Reinforced Filaments

PETG-CF or PA-CF (carbon fiber filled) filaments offer excellent stiffness-to-weight ratios. They are more expensive and harder on nozzles (use hardened steel), but for frame components and structural parts, the weight savings can be significant.

Designing Drone Parts for 3D Printing

Weight Is Everything

Every gram matters on a drone. Design with thin walls (1.2-1.6mm for TPU, 1.6-2.0mm for PETG), use gyroid infill instead of solid fills, and add material only where stress concentrates. A 5-gram weight reduction on a 250-class quad improves flight time, responsiveness, and crash survivability.

Design for Crash Survival

• Use fillets and rounded edges — sharp corners concentrate stress and crack first.
• Orient print layers so that crash forces press layers together rather than pulling them apart.
• For camera mounts, design breakaway points that sacrifice the mount to protect the camera.
• Include zip-tie channels and screw mounting options for redundant attachment.

Mounting Interfaces

Standardize on common mounting patterns:

• 20x20mm — Standard mini flight controller and ESC stack mounting.
• 25.5x25.5mm — Whoop-class flight controller mounting.
• 30.5x30.5mm — Standard full-size flight controller and ESC stack mounting.
• M2 and M3 screws are the most common hardware in the FPV hobby.

Tolerances

3D printed parts need clearance for screws and press fits:

• Screw holes: Design 0.2-0.3mm larger than the screw diameter for clearance holes.
• Press fit holes: Design 0.1-0.15mm smaller than the part being inserted.
• Sliding fits: Add 0.3-0.5mm clearance.
• Always test-print mounting interfaces before committing to a full part.

Full 3D Printed Drone Builds

While most pilots use carbon fiber frames with 3D printed accessories, fully 3D printed drones are viable for certain applications.

As Hackday covered, the community continues to push the boundaries of what 3D printed vehicles can achieve. For drones specifically, ApexRapid's guide documents how 3D printed frames allow for complete design flexibility and customization.

A typical fully 3D printed drone build requires:

Printed components:

• Frame (PETG or PETG-CF)
• Camera mount (TPU)
• Antenna mounts (TPU)
• Motor mounts (PETG or PETG-CF)
• Landing gear (TPU)
• Battery tray (PETG)
• Electronics canopy (TPU)

Purchased electronics:

• Flight controller (Betaflight or iNav compatible)
• ESC (Electronic Speed Controller) — 4-in-1 recommended
• Motors (brushless outrunners, matched to frame size)
• Propellers
• Radio receiver (ExpressLRS or Crossfire)
• Video transmitter and camera
• LiPo battery
• Radio transmitter (controller)

FAA Regulations for Custom Drones

If you are in the United States, the FAA's recreational flyer rules apply to any drone you build, including 3D printed ones.

Key Requirements

• Registration: Drones weighing 250 grams (0.55 lbs) or more must be registered with the FAA. Registration costs $5 and lasts three years.
• TRUST test: All recreational drone pilots must complete The Recreational UAS Safety Test and carry proof of completion. It is free and takes about 30 minutes.
• Remote ID: As of 2025, all registered drones must broadcast a Remote ID signal. Drones under 250 grams used recreationally are exempt.
• Visual line of sight: You must maintain visual line of sight with your drone at all times. FPV goggles are permitted if you have a visual observer who can see the drone.
• Altitude limit: Maximum 400 feet above ground level for recreational flying.
• Airspace authorization: Use the B4UFLY app or LAANC system to check for airspace restrictions before flying.

Weight Considerations

3D printed frames are often heavier than equivalent carbon fiber frames. If your custom drone is close to the 250-gram threshold, weigh it carefully with a battery installed. Being under 250 grams provides significant regulatory simplification, particularly around Remote ID requirements.

Where to Find Printable Drone Part Files

The FPV community is generous with file sharing. Here are the best sources:

• 3DSearch — Search across Thingiverse, Printables, MakerWorld, and other platforms for drone parts, mounts, and frames. Search for your specific drone frame name plus the part you need.
• Thingiverse — The largest repository, though search can be frustrating. Use specific search terms like "iFlight Nazgul GoPro mount."
• Printables — Growing collection with better search and curation than Thingiverse.
• WREKD Co. — Sells pre-printed parts and offers custom printing services. Their designs are available for purchase or inspiration.
• RaceDayQuads — Offers a wide selection of printed FPV parts organized by drone frame model.

Tips for Printing Better Drone Parts

1. Dry your TPU. Flexible filament absorbs moisture quickly, leading to bubbles and poor layer adhesion. Dry at 50°C for 4-6 hours before printing.
2. Use a direct drive extruder. Bowden tube printers struggle with TPU. If you have a Bowden setup, print at extremely slow speeds (15 mm/s).
3. Print mounts with higher infill. Camera mounts and structural parts benefit from 40-60% infill. Use lower infill (20-30%) for protective components like prop guards.
4. Orient for strength. Print camera mounts so the mounting holes go through the strongest axis. Layer lines perpendicular to stress directions are weakest.
5. Test fit before flying. Print test pieces to verify screw hole sizes and mounting interfaces before committing to a full print.

Final Thoughts

3D printing has become an indispensable tool for drone builders. The ability to design, print, test, crash, and reprint a part in a single afternoon accelerates the learning and building process enormously. Start with simple TPU camera mounts and antenna holders, then gradually work toward more complex frame components as your design skills improve.

The FPV community thrives on sharing designs and knowledge. Publish your successful designs on Printables or Thingiverse so others can benefit, and do not hesitate to iterate — every crash is a design opportunity.

Happy printing, and happy flying!
