3D Printing Custom Drone Parts: Frames, Mounts, and Accessories
3D printing has transformed the way FPV pilots build and repair their quadcopters. Instead of waiting weeks for a replacement part or paying premium prices for a niche mount, you can design and print almost any accessory overnight on a desktop printer. From camera mounts to antenna holders, 3D printing gives you the freedom to build a drone that fits your exact needs.
What You Can and Cannot Print
Not every part of a drone is a good candidate for 3D printing. The frame arms and load-bearing structure should stay carbon fiber, because printed plastics flex and fail under crash loads. However, the non-structural parts are perfect for printing: camera mounts, antenna mounts, GoPro holders, battery straps, skid plates, GPS mast mounts, and protective bumpers all work beautifully in PETG or TPU.
The Right Filament for the Job
Choose your filament by function. PLA is easy to print but brittle and melts in the sun, so it is best for prototyping and indoor parts. PETG offers a good balance of strength, flexibility, and heat resistance for outdoor mounts. TPU is the superstar for drone parts because its flexibility absorbs vibration and survives crashes that would shatter rigid plastic. For most functional drone accessories, PETG and TPU are the go-to materials.
Print Settings That Matter
Drone parts are small but need to be tough. Use at least three to four perimeters and 30 percent infill for structural parts, and higher infill for anything that carries a camera. Layer height between 0.16mm and 0.2mm keeps detail while printing fast. For TPU, slow the print speed down to 20-30mm per second and disable retraction to avoid jams.
Designing Your Own Parts
Free tools like Fusion 360 and Tinkercad make it easy to design custom mounts even for beginners. Measure your component with calipers, add 0.2mm of clearance for a snug fit, and design for print orientation so the layers run along the load direction. Popular model sites also host thousands of ready-made drone parts you can download and print in minutes, which is a great way to learn what good designs look like.
Replacing Parts After a Crash
The real power of 3D printing shows up after a crash. When you snap a camera mount or lose an antenna holder, you can print a replacement the same evening instead of waiting for shipping. Keep a small library of your most frequently broken parts saved so you can reprint on demand. This is also where TPU shines, since flexible parts often survive impacts that would break a rigid original.
Practical Projects to Start With
If you are new to printing drone parts, begin with low-risk projects. A battery strap holder or an LED light mount is a quick win. A motor mount or antenna mount teaches you about tolerances and fit. As you gain confidence, move on to a full TPU action-camera mount or a landing skid. Each project builds your skills for the next, and before long you will be designing custom parts that are better than anything you can buy.
Final Thoughts
3D printing is the perfect companion hobby for FPV pilots. It lowers repair costs, enables rapid prototyping of custom quadcopter accessories, and gives you a reason to keep your printer busy. Start with a simple camera mount or antenna holder in TPU, and you will quickly see why so many pilots keep a printer next to their workbench.
