F450 quadcopter drone landing gear

These are 100mm tall and fit the powerday f450 quadcopter kit. They may fit others - unsure. They're designed to slip in openings and utilize the kit screws where the bottom plate attaches to the arms and fit in between the solder contacts, if you're using the bottom plate as power distribution for stand alone ESCs. 

I printed using the bambu PETG .20mm strength setting and made the first 42 layers solid to ensure that the whole thing is solid. They weigh about 10g each.  I've dropped it a couple of times and flew the drone into the house after some spectacular forward flips, while I was learning to fly this one, and the legs are still functioning perfectly.
