On the second flight test of the Crazyfly I broke one of the quadcopter arms. Something I imagine happens frequently as they are very brittle.

This 3D print model reinforces the existing arms and allows broken arms to be used.

Currently the model seems to be a bit on the heavy side, although that could be an issue with my Crazyflie settings.


Print on a suitable 3D printer with support structure.

I use ReplicatorG to load the STL to generate the gcode for MakerBot I.

Model may have to be centered to cover the print area properly.

I've now included the SCAD file (horrible as it is.) Please hack and chop. It contains a couple buried options to have fully circular bumpers and other things. (like thinner structure support, which couldn't get printed properly on the MakerBot)

Hey Petr, Can you please let me know what material you have used to print the frame?

Looks like the attached OpenSCAD file is actually for a different model

Great idea! Can't wait to print my own and give it a try!

Hey petr, would you be comfortable sharing the (OpenSCAD?) source file as well?

Hi, Done! Its my first biggish SCAD program, so it kind of a code hack.

Awesome, thanks!
