3D Printing Meets FPV Ground Equipment
We spend so much time optimizing our quads that ground equipment often gets neglected. But your goggles, radio, and ground station are where you spend 100% of your flying time. 3D printing lets you customize every aspect of your ground setup for comfort, performance, and ergonomics. Here is how the community is using printed parts to elevate the pilot experience.
FPV Goggle Upgrades and Mods
Comfort and Fit
The single best upgrade for any goggle is a custom TPU faceplate. Stock foam faceplates degrade, absorb sweat, and rarely fit perfectly. A printed TPU face gasket can be tailored to your face shape and pairs with aftermarket foam or silicone seals. Designs exist for DJI Goggles 2/3, Fatshark HDO, Skyzone, and Walksnail Goggles X.
For glasses wearers, printed diopter holders let you insert prescription lenses into the goggle optics path. Much more comfortable than wearing glasses inside goggles and eliminates fogging between glasses and lenses.
Cooling and Anti-Fog
Goggle fog ruins sessions. A small 25mm or 30mm fan mounted in a printed bracket actively circulates air through the goggle cavity. Power it from the goggle battery or a small separate 1S LiPo. Many designs use standard 25x25mm 5V fans that cost $2 on Amazon. The fan can run continuously or be switched — some pilots wire it to a PWM controller for variable speed.
Antenna Upgrades
Printed antenna mounts replace the fragile stock SMA connectors. Popular designs include:
- Triple-feed patch + dual omni: One directional patch antenna plus two omnidirectional stubbies for 180-degree coverage
- Helical antenna mounts: Large 7-12 turn helical antennas need rigid mounting — printed brackets prevent the heavy antenna from stressing the SMA port
- Quick-disconnect adapters: SMA-to-MMCX adapters in printed housings for rapid antenna changes between analog/digital VRX modules
Power Solutions
Stock goggle battery straps are universally terrible. Printed solutions include:
- 18650 battery holders: 2S or 3S configurations using common 18650 cells (Samsung 30Q, Sony VTC6). Much more capacity than stock LiPos in the same form factor.
- Head strap cable management: Integrated channels route the power cable along the head strap instead of dangling.
- Power bank mounts: For goggles that accept USB-C PD input (DJI Goggles 3), a printed bracket holds a compact 10000mAh power bank on the head strap for all-day flying.
Building a DIY Ground Station
A ground station takes the video receiver out of your goggles and puts it on a tripod with a directional antenna — dramatically improving range and signal quality. Typical components:
- Tripod adapter: A 1/4-20 threaded insert printed into a bracket that holds everything. Standard camera tripod threads mean any tripod works.
- Diversity receiver mount: Holds two VRX modules (like RapidFire or TBS Fusion) side by side. Printed enclosure with ventilation slots and cable routing.
- Antenna tracker (advanced): A GPS-equipped Arduino or ESP32 reads telemetry from the drone and physically points a directional antenna. All mechanical parts — pan/tilt brackets, gear mounts, enclosure — are 3D printed. The open-source u360GTS project is a great starting point.
- Monitor integration: A 7-10 inch LCD monitor mounts above the VRX. Printed sun hood prevents glare. HDMI or composite video input from the diversity controller.
- Battery management: Large 3S-6S LiPo (2200-5000mAh) in a printed tray powers everything for hours. Include a voltage display and low-voltage alarm.
Radio Transmitter Customization
Your radio is the primary interface — make it fit your hands perfectly:
- Custom gimbals: Extended stick ends in various shapes (rounded, pointed, hybrid) printed in TPU for grip
- Switch identification: Color-coded TPU switch covers make it easy to identify arm, mode, and beeper switches by feel
- Grip enhancements: Contoured TPU grips that slide onto the radio body, massively improving ergonomics on box-style radios like the Radiomaster Boxer
- Module bay covers: For radios with external module bays (TX16S, Boxer), printed covers protect the pins when flying internal ELRS
- Screen protectors and shades: Printed frames hold cut acrylic or glass screen protectors; hoods improve outdoor visibility
Getting Started with Goggle and Ground Station Mods
Search Thingiverse and Printables for your specific goggle model — the most popular goggles have dozens of community designs. Start with a TPU faceplate (most impactful comfort upgrade) and a fan mount (solves fogging forever). Total cost: $5 in filament and a $2 fan.
The ground station is a more involved project but transforms long-range flying. A basic tripod-mounted diversity setup with directional antennas can double your usable range compared to goggle-mounted omnis. The 3D printed enclosure integrates everything into a clean, portable package that deploys in 30 seconds.
Every part of your FPV ground equipment can be improved with thoughtful 3D printed mods. The barrier to entry is low — a single spool of TPU and PLA covers almost every project here, and the STL files are free and abundant.
