This is a landing gear strap I made for my FT 3D RC airplane. The stock plane uses a rubber band to hold the landing gear on, but the rubber bands were always breaking, so I decided to design these. You can easily find these in a hobby shop, but they are rather expensive for what they are. The store-bought ones are usually nylon, and probably more rugged than the PLA ones I made, but these are cheap and served as my first design in Fusion 360.
