FPV Drone Repair Parts: Print Your Own Replacements

An FPV drone crash breaks the cheap parts first, and that is good news if you own a 3D printer. Camera mounts, antenna mounts, landing feet, and guards are all simple prints, and FPV drone repair parts printed at home cost a few cents each. Instead of waiting days for a replacement mount, you print one in an hour and fly the same day. This guide covers the FPV drone repair parts worth printing, the materials that survive crashes, and when to print and when to buy the real part.

FPV drone repair parts you can print tonight

Start with the parts that break every crash: camera mounts, antenna mounts, and landing feet. A camera mount takes the first hit in most crashes, and a printed replacement in PLA+ will hold the camera square and survive the next one. PLA+ is tougher than standard PLA, less brittle, and holds up better under impact, with stronger layer to layer adhesion. That makes it the default filament for drone parts. PLA+ filament comes as a full 1KG spool, ready to print, and Anycubic PLA+ is the same material as a lower priced refill coil that needs a reusable spool. Antenna mounts are the same story. A printed flex mount is ideal, but a PLA+ mount with a little give will protect the antenna in most crashes. Print two or three at a time, since they are small and cheap, and keep them in your field box.

Guards and bumpers belong in PETG. A camera guard or motor guard needs to flex on impact, and PETG flexes instead of snapping. Its impact resistance is twice that of standard PLA, and it holds up in humid conditions. Anycubic PETG prints guards that take hits and keep the camera and motors safe. For parts near motors or ESCs that run hot, use Polymaker HT-PLA Pro. It has high heat stability, prints up to 300mm/s, and you can anneal it at 100C for 30 minutes for the best heat resistance. A motor mount or ESC cover in HT-PLA Pro will not soften next to a warm motor.

Camera mounts and antenna mounts

Camera mounts deserve the most care, since a loose camera ruins the footage and a tilted camera ruins the flight. Print camera mounts in PLA+ with four walls and 40 percent infill, and check the fit before you fly. The camera should sit tight with no play. If the mount flexes in your hand, add walls or reprint it in a stiffer orientation. Antenna mounts need the opposite: a little flex. An antenna mount that is too stiff will transfer the crash straight to the antenna and snap it. Print antenna mounts with three walls and orient them so the layer lines run across the load. A mount that bends and springs back saves the antenna, and a broken mount costs a few cents to replace.

While you have the printer running, print the small parts that always go missing: landing feet, GoPro mounts, and buzzer holders. These parts are simple, they break often, and a printed spare in the field box saves the flying session. Keep a few of each in the box, and print a fresh batch when the box gets low. The printer earns its keep on these parts alone, since buying them one at a time costs more in shipping than the part is worth.

When to print and when to buy

Print the plastic parts. Buy the electronics. A printed camera mount is as good as a bought one, but a printed receiver is not a receiver. When a crash kills the electronics, replace them with real parts. The 2.4G ExpressLRS ELRS receiver is a 2.4G ExpressLRS receiver for FPV freestyle and long range, and it is the part to buy when the old receiver stops binding or drops signal. The 15A High-Voltage UBEC is the part to buy when your power setup needs a clean, stable supply for a 6 to 12S LiPo build. A DJI Neo 2 landing gear frame is a simple bolt on upgrade that protects the drone on landing. Print what you can print, buy what you cannot, and keep flying.
