Railcar Chassis

Now on Printables.com too.

Continuing a theme that started with the Mine trolley for Stop Motion and seems to have developed a life of its own, here is the development that has been bubbling away in the background for some time. This is a railway chassis for 1:24 scale car models. It is designed to fit 1:24 scale standard gauge tracks.

I have found that it works really well with Die-Cast muscle cars from Maisto and MZ. I have also built one using the DeLorean Model by heisenberg333. Scaling the Delorean model down to 1:24 scale was a bit problematic at printing time. There are no shortage of very cool looking car models on Thingiverse. You may need to modify the Mainframe component (Railcar-Mainframe.stl) to fit whatever model you choose to use, but I have set up the mesh to be quick and easy to modify with any halfway descent modeler capable of working at the vertex and polygon level.

The component filenames include the number of items you require of each. For instance Railcar-BogieInSidesx4.stl needs to be printed four times. If there is no number noted, then just print it once.

In the downloads there is an assembly guide: Railcar_Chassis_Assemblyv0.pdf

Additional things you will need;

• A 1:24 scale car body
• Some 4mm diameter dowel for axles and locator pins (or M4 threaded rod)
• M4 x 10mm dome head cap screws, washers, and nuts to secure the bogies to the frame (if you want them to move that is)
• Some wire for pipes (7.5A insulated wire is about the right size)

Here is the list of my previous projects that have been incorporated into this project;

• Bogies for 1:24 Scale Standard Rail Gauge
• Parametric footplate
• Vintage Railcar
• Railbike Chassis

Happy building

Update 3rd Feb 2019

If you are looking for tracks to display it on, then have a look at these parametric track models. You will just need to set the track gauge to 60mm and sleeper length to 80mm to be compatible with this model.
