140 Sized Quadcopter - By 3DEX

3D model description

This is our 140-size quadcopter frame that is easy to print, easy to assemble and easy to fly. We have found that the frame is virtually indestructible. We made it using our Black ABS filament.

Be sure to buy your 3D printer filament from if you want the same great results!

We wanted to design a small quadcopter frame that could be printed on most standard sized 3D printers. However, we also wanted the quadcopter to be able to use standard sized electronics. Therefore, we decided to make the motor mounts larger (this frame will accept 22-XX sized motors). This then created a need for wider frame arms. We also designed the frame for a standard sized flight control board. We ran a Naze32 but intent to fit a Raceflight Revolt soon.

The frame is big enough to run 3.5" props which we would recommend. After using only 3" props we upgraded to 3.5x4.5" props for better flight characteristics. This quad frame would be an excellent FPV racer and we will be updating this design to include an FPV camera and TX mount that will go above the flight control board.
