Introduction
Beyond frames and camera mounts, a 3D printer can produce dozens of useful accessories for your FPV drone fleet. From protective gear to organizational tools, these prints improve safety, convenience, and longevity — often costing pennies in filament.
This guide covers the most practical 3D-printed FPV accessories, organized by category. Every item listed has been community-tested and proven useful in the field.
Protective Accessories
Motor Bumper Guards
Small TPU rings that fit around the bottom of your motors, extending slightly below the motor bell. In a hard landing or crash onto a hard surface, the bumper hits first, protecting the motor bearings and windings. Designs exist for all popular motor sizes (22xx, 23xx, 14xx, 16xx). Print at 100% infill for maximum impact absorption.
Arm Skids / Landing Pads
TPU skids that clip onto the ends of your frame arms. They serve triple duty: landing protection, motor protection in inverted crashes, and visual orientation aid (print in bright colors for front/rear differentiation). For 5-inch frames, design the skid to extend 3-5mm below the motor.
GoPro / Action Camera Mounts
Perhaps the most-printed FPV accessory. A well-designed TPU GoPro mount provides:
- Crash protection for your expensive action camera
- Vibration isolation (especially important for GoPro Hypersmooth)
- Adjustable angle (typically 15-35° for freestyle, 40-55° for racing)
- ND filter retention slots
For 2026, mounts compatible with GoPro Hero 11/12/13 Mini, DJI Action 2/4/5, and Insta360 GO 3S are most popular.
Battery Pad / Anti-Slip Mats
Print thin TPU sheets (1-2mm) with a textured surface to place between your battery and the top plate. They prevent battery slippage during aggressive maneuvers and absorb vibration. Many pilots print these as “battery condoms” — a TPU sleeve that wraps the bottom third of the LiPo for grip and light impact protection.
Capacitor Holders
Low-ESR capacitors on your ESC power leads are essential for clean power, but they’re bulky and awkward to mount. A printed TPU capacitor holder clips onto the frame and secures the capacitor, preventing it from rattling around or ripping solder pads in a crash.
Organizational Accessories
Prop Storage Boxes
Props multiply quickly. A printed prop storage box with dividers keeps your collection organized by size, pitch, and condition (new vs. slightly scuffed but flyable). Design with labeled compartments for 3-inch, 3.5-inch, 4-inch, and 5-inch props.
Battery Storage Racks
Wall-mounted or toolbox-ready battery racks keep LiPos organized by cell count and condition. Key features: individual slots for each battery, label tabs, and fire-resistant design considerations (air gaps between batteries). Important: always store LiPos at storage voltage (~3.8V/cell) in fire-resistant containers — the printed rack is for organization, not primary fire protection.
Tool and Screw Organizers
M2 and M3 hardware, standoffs, nuts, and washers are the lifeblood of FPV builds. A grid-based organizer with labeled compartments for M2x6, M2x8, M3x10, M3x12, standoffs, locknuts, and prop nuts saves hours of searching. Modular designs let you expand as your hardware collection grows.
Work Mat / Soldering Jig
While silicone work mats are standard, a 3D-printed soldering jig that holds your flight controller or ESC at a comfortable angle makes precise soldering much easier. Add XT60/XT30 connector holders, wire guides, and a magnifying glass mount for a complete soldering station.
Field Accessories
Battery Checker Cases
Those simple 1-8S battery checkers are fragile. Print a protective TPU case with a screen window and button access. It’ll survive being tossed in your flight bag.
SD Card Cases
Micro SD cards are easy to lose. A credit-card-sized TPU holder that stores 4-8 cards in individual slots is essential kit. Some designs include a label area for marking which card holds which footage.
Video Antenna Signal Flag
Print a small flag with your channel and band displayed prominently. Clip it to your ground station antenna. At multi-pilot events, it prevents accidental channel conflicts and helps identify your setup.
Goggle Lens Protectors
Your goggle lenses are expensive and easily scratched. A snap-on TPU lens cover protects them in your bag. For DJI and Walksnail goggles, designs include cutouts for the proximity sensor so the goggles still auto-sleep properly.
FPV Simulator Accessories
Radio Gimbal Protectors
Protect your transmitter’s gimbals during transport. A TPU plate that clips onto the radio face prevents the sticks from being bent or broken in your bag. Designs exist for Radiomaster TX16S, Boxer, Zorro, Jumper T-Pro, and FrSky X9D+.
Simulator Stand / Phone Mount
If you practice on a phone or tablet (Liftoff, DRL Sim), a 3D-printed stand holds your device at the right angle while you fly. Some designs integrate a radio tray for a complete sim practice station.
Printing Recommendations
- Impact protection: TPU 95A, 3-4 perimeters, 40-60% infill
- Organizational items: PLA or PETG, 2-3 perimeters, 20% infill
- Vibration isolation: TPU 85A-90A (softer), 2 perimeters, 30% infill
- Structural jigs: PETG or ASA, 4 perimeters, 40% infill
Conclusion
The beauty of 3D printing for FPV is that you can solve your own problems. Break a motor in a hard landing? Print bumpers. Can’t find your M2 nuts? Print an organizer. Fed up with SD cards scattered everywhere? Print a case. Every accessory in this article costs less than $2 in filament — and the designs are all available free from the FPV community. Fire up your slicer and start printing.
