Eachine Aurora 90 Prop Guard Bracket

This is a prop guard bracket for the Eachine Aurora 90mm quadcopter frame. I'm using Racerstar BR1103 motors, which are shorter than the standard 1104 motors typically used with this frame. I discovered that the props were hitting the stock aluminum prop guard brackets, so I designed this bracket as a replacement. I gives a bit more clearance for the props than the standard bracket.
