Propeller protection

I designed theese propeller guards to change the broken ones from banggood. I also separated the model onto 2 parts for easy printing - you only need 3xM2 screws and nuts to assemble it. This guards are suitable for 1104 motor holes (4x2.5mm holes in 9 mm diameter).
Anyway, the source files for solidworks are included - you may easily change the fixing holes for your needs.
