CrazyFlie protective cage

I needed a cage, and after months of work, came up with this.
Print with 0.2 nozzle, high settings.
Printed with PLA, but you can do PETG or ABS if you want.
It's made of 4 parts.
The prop holders, smaller than the factory ones. Replace the old ones, put motors inside.
The line thingie goes underneath in the gap.
Use the bottom ring to join all 4 line thingies together. Superglue recommended. It does not obstruct the view of the sensor below.
On top, print the top ring, put the 4 line thingies inside, use superglue, and voila!
