Weighing at around 2.8grams, this frame clips onto the Crazyflie 2.0 to provide protection for the propellers.
The design is based on a similar prop guard
I made for the original Crazyflie 1.0.
The 2.0 prop guard has a similar frame flex/stiffness as the 1.0 guard and is revised to suit the new PCB board shape and the slightly more spread out motor positions. The clip-on contact points are also re-designed for a more secure and evenly-distributed attachment.
The custom motor mounts
shown in the photos are also available here at Shapeways.
