CrazyFlie 2 propellor guard

thingiverse

For the CrazyFlie 2, not its original version. X-axis and Y-axis protection is all that's required. We generally don't need Z-axis protection, so we're keeping it out to minimize weight. Printed on a Flashforge Creator Pro with a 0.4mm nozzle diameter in BPA plastic. Remove the props (handle them with care) and position the part over the motors. This safeguard has prevented countless propeller and motor mount losses.
