Rail-Car Hybrid Model Chassis

Here is a development that has been bubbling away in my sketchbooks for some time. It 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. There are no shortage of very cool looking 3D printable car models around. You may need to modify the main frame 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 using any halfway descent modeling program 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 you will find 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)

All parts will print without support.

Here is the list of my other projects that are related to this project;

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

If you are looking for tracks to display your model 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.
