Small legs to raise the multi rotor up off the ground.These are designed to fit 1/2 inch (12.5mm) square wooden booms. Two holes allow for zip tie mounting. Note: Mounting 'Fork' was designed to be slightly short on purpose. This allows the zip tie to 'bite' into the boom. Note 2: The backs of the legs are hollow to save on plastic and print time (look at 3d view to see better).The part is 144mm long (prints diagonally on printrbot simple metal). Will likely require platform adhesion assistance.
