I updated the STL file to include the shock absorber lines on the original landing gear.
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/dx7Dop1MsUi
I printed in Silver for a special restore I am doing. Print in black to match the original. These fit nicely and I have the stop just right so it pushes into the gear well and stays there then stays down when moved.
Print in 2 pieces and CA glue them together. Picture shows the original next to my printed gear. :)
