Thingiverse
A super simple post cap for many postwar Lionel accessories. It will fit on an 7.5x7.5mm post, the standard of the time. The official part number is 62-3. I made the walls 1.5mm so it would have some rigidity, but it is a little thick. I am okay with it, but if you need it thinner, please comment and I will change the design accordingly.
