Spyda / Crossfire Quadcopter Arm with removable / replaceable foot

thingiverse

To address my quadcopter's issue of breaking feet after hard landings, I designed a more stable foot (available at http://www.thingiverse.com/thing:229300). However, it requires 4.5 hours to print with 50% infill. Thus, I developed an arm with replaceable feet for easier replacement and faster flight time. Simply remove the broken piece with pliers, insert a spare part, and resume flying quickly while conserving filament and money. The foot's tight fit in the hole ensures it won't fall off during flight, although it may be challenging to insert on some printers.
