In the past I have collected and adapted quite a few models to make them suitable for 3D printing, which I find a great way to improve the hobby and expand my fleet of rolling stock. Below you can find updated renderings of most of the cars I made (or adapted) and 3D printed over the years. With more to come.
62ft Woodchip Gondola
This car has a build report (in German, sorry)
63ft Bulkhead Flatcar with „Log-Bunks“
54ft PS2 „High Side“ Covered Hopper
This model was entirely modeled by me in Blender using the corresponding Proto2000 HO scale model for reference and measurements and features brake details, fine scale ladders and grab irons as well as some nuts and bolt details. The design cost me the better part of two weeks modeling, some 50 hours in total.
This model has some commercial quality, so the STL file will not be available, I’m afraid.
50ft Bulkhead Flatcar
This car also has a build report (in German, sorry)
62ft Skeleton Logcar (WIP)
62ft NSC Bulkhead Flatcar (WIP)
50ft Jordan Spreader (Type 2)
40ft Snow Plow
73ft Centerbeam Flat Car
New renderings will follow shortly


My ressources are primarily from 3D Warehouse, even though None of the Models comes 3d printable.
