Quadcopter Frame

thingiverse

Quadcopter frame with interchangeable components and shock-absorbing landing gear. Requires printing 1 base, 1 top, 4 arms, and 4 legs. Only compatible with 5-inch propellers. Designed for small parts that can be printed on an M3D printer. Uses #4 screws 12-5/8 inches long to attach the arms to the base, and #4 screws 7/8 inches long to connect landing leg to arms. May require washers for each screw. Needs 16 #4 nuts with self-locking threads or blue thread locker. Requires 4 springs with 1/4 inch internal diameter and 1 1/4 inch length. Originally planned to use the kk260 FPV plate, but it didn't work out so I redesigned the base and added a top; still needs extensions from that kit or similar tubes 0.125 inches in diameter. Print Settings: Printer Brand: LulzBot Printer: TAZ 5 Rafts: Doesn't Matter Supports: Yes Resolution: 0.5mm Layer Infill: 20% Notes: I used 0.5mm layer thickness but printing slightly smaller would help with arm detail since the rounded part of the arms needs a little more definition towards the end. The only parts that require supports are the legs to print the spring attachment point properly. May need to flip base and arms for easier printing. Printed with ABS, but PLA should also work. The ABS has advantages because it can be cleaned up with acetone and bonded loose spots. Design Process: SolidWorks I was tired of replacing entire frames after hard crashes, so I needed a modular frame design. Custom Section: Add-ons Originally designed to use the KK260 FPV Racing frame plate but made some dimension mistakes; when corrected will upload revised base.
