Removable N Scale Hayes Bumper I made this yesterday. Thought it turned out pretty good so I decided to share it. https://www.thingiverse.com/thing:4007446
It is a site that hosts free STL files for you to download and 3D print on your own. There is quite a lot of Model railroad stuff on it in HO and N.
Ok, thanks! I don't have a 3D but that is interesting. Now? How about containers with windows cut out? Just a thought. ☻
