This is a proper guard for the Cheerson Cx-10 Mini-Drone, it is intended to be lightweight whilst providing a simple and clean aesthetic look for the CX-10.
I've seen some other prop-protectors that I liked but they were not quite what I was looking for.
There are two versions of the light-guard;
. CX-10-Light-Guard-Robust: is a robust guard that was thickened in testing until it held up to crash abuse well. It can still break in heavy collisions but is far more likely to save your prop if it does, having absorbed the most of the impact energy. In general use it have proven to remain intact and unbroken. Four of these will add around 1 gram to the flight weight.
. CX-10-Light-Guard-Feather: is a lighter version of the light-guard intended to reduce the effect on increased battery drain that I noticed in use of the Robust-version. It is more prone to breakage but will likely protect your props none the less. Four of these will add around 0.5 grams to the flight weight.
I've printed it in PLA at 0.2mm layer height and it has printed fine.
