Rubber Landing Gear for Small Quadcopters

thingiverse

Some people like to mount their batteries on top of their small quadcopters, but I like to mount mine on the bottom closer to the center of gravity. And these landing gear raise my quadcopter up enough to do this. They also help soften hard landings--if you print them with Ninja Flex. I would recommend using long screws to reduce the amount of bounce these tend to have. I am using 3mm X 35mm cap-head screws in mine. These would probably work with ABS too.
