Simple replacement landing gear for a Turnigy Talon V2 carbon fiber quad copter. I found that the original parts were very easy to break, even from a soft landing and they around $10 to replace to i had to find a cheaper alternative.
If you print it at a medium infill (50%) it's flexible enough to absorb a bit of impact without breaking.
Should work well with http://www.thingiverse.com/thing:162908 if you drill a small pilot-hole and use a self tapping screw
nice easy print, 50% infill to add a bit of flex but still strong. i printed with 3 shells but it really doesn't matter.
