Landing gear leg for 1/72 scale model kit of Messerschmitt Bf 108 Taifun. I made this for a shortrun kit by Fly (also reboxed by AZ Model).
It is not very true to the real thing, but still looks so much better than the kit parts.
Mirror the model to get both legs. Print from a regular resin (legs are sturdy enough to hold a small light aircraft model). The SL1 file contains 3 pieces of each leg.
