Main objective of this project was precisely to ensure sealing of the prop-guards in case of impacts, also allowing to mount and unmount these accessories just in few seconds without using screws.
I guess that in case of strong impact, the Phantom could be much more damaged by prop guards mounted using the screws that hold in place the motors in their plastic bases...
Anyway, I made these prop-guards with a professional-grade 3D printer (ZORTRAX M200), using high-quality impact resistant materials (Z-HIPS).
The grip is very strong and elastic enough to allow the perfect snap-on of the prop guards.
I tried to drive the drone against some walls at different speeds and angles: the results were very satisfactory and the prop-guards have never detached from the arms of the Phantom 3.
However, if you don't have a 3D printer, the "Easy Snap-On Prop Guards" are available as a ready to use kit for your Phantom 3 at € 22.90 EUR + shipping.
They are made with a professional-grade 3D printer, using high-quality impact resistant materials for best results.
I imagine a guy named Giuseppe Finizia is in like a fancy tux, and then the butler says, 'may I present, Giuseppe Finizia' and everyone is all, 'whoa....' As you come down the stairs with some hot younger woman on your arm, and the crowd is all quiet.
