10 Essential 3D Printed Upgrades Every FPV Pilot Should Print in 2026
There’s a beautiful symbiosis between FPV drones and 3D printing. Drones break. Printers make replacements. Drones need custom mounts for odd-shaped components. Printers handle that in an afternoon. It’s the closest thing the hobby has to a self-sustaining ecosystem, and if you’re not taking advantage of it, you’re spending more money and waiting longer for parts than you need to. Here are ten prints that every FPV pilot should have in their arsenal — parts that solve real problems, save real money, and in some cases, improve your flying experience in ways off-the-shelf parts can’t match.
1. TPU Camera Mounts and Cages
This is the gateway print for most FPV pilots, and it remains the single highest-value thing you can print. A well-designed TPU camera mount does three things: it isolates your camera from frame vibrations (cleaner video), it absorbs impact in a crash (fewer broken cameras), and it lets you adjust camera angle without tools or shims. In 2026, the open-source designs on Thingiverse and Printables have gotten incredibly refined — mounts with integrated ND filter slots, cable management channels, and even tilt mechanisms that lock into preset angles. Print at least three at a time. You’ll use them.
Material recommendation: TPU 95A. Softer TPU (85A) provides better vibration isolation but can let the camera shift during aggressive flight. Harder TPU (98A or D40) holds position better but transmits more jello. 95A is the sweet spot for most builds.
2. Antenna Mounts (VTX and RX)
Your antenna is the most vulnerable part of your quad, and zip-ties plus heat shrink only get you so far. A rigid TPU antenna mount — either as a standalone piece or integrated into a rear bumper — protects your SMA/MMCX connector from direct impact and holds the antenna at the optimal angle. For long-range builds, print a mount that angles both antennas at 45 degrees (the optimal orientation for linear polarization at cruising pitch). For freestyle, a low-profile mount that keeps the antenna behind the frame profile will save you from the dreaded “antenna snagged on a branch, quad spinning into the abyss” scenario.
Print the RX antenna mount separately from the VTX mount. RX antennas (especially the immortal-T style) need different geometry than VTX antennas, and combining them into one part creates a single point of failure.
3. Arm Guards and Skid Plates
Carbon fiber arms are tough, but they’re not immune to edge delamination from repeated ground strikes. A set of TPU arm guards — thin, snug-fitting sleeves that wrap around the end of each arm — dramatically extends the life of your frame. The key design feature to look for is a slight flare at the motor end that acts as a bumper, absorbing the initial impact before it reaches the carbon. The best designs in 2026 also incorporate a small skid at the bottom that keeps your motor screws off the ground when you land on concrete.
Don’t overbuild these. Arm guards that are too thick add rotational inertia at the motor, which the flight controller has to fight. Keep wall thickness at 1.2mm to 1.5mm for a 5-inch build — enough to absorb impact without meaningfully affecting flight performance.
4. GoPro and Action Camera Mounts
The off-the-shelf GoPro mounts that come with frames are universally mediocre. They’re designed to be “good enough” for everyone, which means they fit nobody’s specific setup perfectly. A custom-printed TPU mount can be tailored to your exact camera, your exact frame geometry, and your preferred angle. Better yet, print a session-style cage that wraps around the entire camera body — this protects the camera in a crash far more effectively than the standard two-point strap mount.
The 2026 innovation worth knowing about: soft-mount GoPro cages with integrated ND filter holders. Instead of threading an ND filter onto your lens every flight (and risk cross-threading or losing it), the filter slides into a slot in the printed mount. Swapping filters mid-session takes three seconds instead of thirty.
5. GPS and Buzzer Mounts
GPS modules and self-powered buzzers are awkward shapes that rarely have a natural home on a frame. A custom printed mount — either zip-tied to a standoff or integrated into the rear of the top plate — solves this cleanly. For GPS, look for designs that mount the module above all other electronics (for best satellite reception) and include a small shield to block RF noise from the VTX. For buzzers, designs that recess the buzzer into the frame with an opening for the sound to escape are far louder than surface-mounted solutions.
If you’re running both GPS and a buzzer, print them as a single combo mount. Consolidating mounts reduces weight, simplifies wiring, and looks cleaner than two separate printed parts flapping around on your frame.
6. Battery Pad Grips and Landing Skids
Battery ejection is one of the most common crash outcomes in FPV, and it’s almost always caused by inadequate grip between the battery and frame. A printed TPU battery pad with an aggressive texture — think a grid of small pyramids or a fish-scale pattern — increases friction dramatically compared to the smooth silicone pads that come with most frames. Paired with a pair of quality battery straps (Kevlar-reinforced, please), a textured TPU pad will hold your pack through crashes that would otherwise send it flying.
As a bonus feature, extend the battery pad downward into landing skids. This protects your battery on rough landings, lifts the frame off the ground for bottom-mounted battery builds, and adds essentially zero weight since you’re printing the pad anyway.
7. Prop Tool and Nut Wrenches
This one sounds trivial, but print it and you’ll wonder why you didn’t do it sooner. A dedicated TPU prop tool — a small, contoured grip that slides over your prop nut and gives you leverage — makes prop changes painless, especially with lock nuts that have been on for 50 flights. Print your own, customize the handle to fit your fingers, and make it bright orange so you can find it in your field bag. While you’re at it, print a prop straightening jig — a small block with the correct prop profile cut into it — for checking bent props during field repairs.
8. Stack Spacers and Vibration Dampeners
The rubber grommets included with most flight controller stacks are fine, but they’re generic and often too soft or too stiff for your specific frame. A printed set of TPU spacers in custom heights lets you dial in the perfect stack spacing for your build. More importantly, you can experiment with different infill percentages to adjust vibration damping: 30% infill for a soft, isolating mount on a noisy frame; 80% infill for a rigid mount on a clean build where you want maximum gyro fidelity.
Combine these with printed nylon standoffs for a fully custom stack mounting solution. Nylon standoffs are lighter than aluminum and won’t short anything if they contact the FC.
9. Canopy and Aerodynamic Shells for Micros
If you fly whoops or micros, a printed canopy is a massive upgrade over the stock options included with most BNF quads. The stock canopies are typically injection-molded in a single piece — light, yes, but fragile and often poorly designed for camera protection. A TPU canopy printed at 0.12mm layer height with integrated camera mounting, antenna routing, and impact absorption is tougher, fits your specific camera better, and can be reprinted for pennies when it eventually breaks.
The open-source micro canopy scene in 2026 is fantastic. Designs are available for virtually every popular micro frame, with variations for different camera sizes, antenna types, and even custom color schemes. A roll of transparent TPU costs $25 and produces dozens of canopies.
10. Workshop Organizers: Battery Checkers, Screw Trays, and Soldering Jigs
This last category isn’t about parts that fly — it’s about parts that make building and maintaining your fleet easier. A 3D-printed screw sorting tray with labeled compartments saves you from the eternal “which screw goes where” puzzle during rebuilds. A soldering jig that holds your XT60 connector and wires in perfect alignment makes power lead soldering faster and cleaner. A battery checker holder that mounts to your field case wall keeps your most-used tool accessible. An ESC flashing jig with pogo pins eliminates the frustration of holding probes on tiny pads.
These workshop prints are the unsung heroes of the FPV hobby. They don’t improve your flying directly, but they reduce the friction of building and repairing, which means you spend more time in the air and less time hunting for a 2mm screw that rolled under your workbench.
Filament Selection Cheat Sheet
Almost everything on this list should be printed in TPU. But which TPU? Here’s the quick guide:
- TPU 95A: The workhorse. Use for camera mounts, antenna mounts, arm guards, GoPro cages, battery pads, prop tools, and canopies. Good balance of flexibility and rigidity.
- TPU 85A: Extra-soft. Use for vibration isolation parts like stack spacers when you’re fighting jello. Harder to print — requires direct drive and slow speeds.
- TPU 98A / D40: Semi-rigid. Use for parts that need to hold shape under load, like structural GoPro mounts for heavy cameras. Prints almost like PLA on a direct drive setup.
- PETG: Only for non-impact parts. Workshop organizers, soldering jigs, prop straightening blocks. Do not use PETG for anything that goes on the quad — it shatters on impact.
- PLA: Prototyping only. Use PLA to test fit and geometry, then reprint in TPU for the final part. Never fly PLA — it will break, and it will break at the worst possible moment.
If you own a 3D printer and fly FPV, you’re sitting on an unlimited supply of custom drone parts. These ten prints cover the essentials, but once you start, you’ll find yourself designing your own solutions for your specific builds — and that’s where the real magic of this hobby intersection lives.
