A little while ago I posted a set of 3D printed railway bogies with the intention of incorporating them into a larger project. This larger project was to build a deck and attach a 1:18 scale motorbike model from Maisto. Here then is the final result, a detailed model railway chassis that could be adapted to other motorbike models.
I should also stress THIS MODEL DOES NOT INCLUDE THE MOTORBIKE. The motorbike is an old Maisto model I bought years ago. There are some good 3D printed motorbike models around that might lend themselves to this project. For instance;
This package is self contained and includes the railway bogie models, so you don't need to rush off and download them as well.
I have included the blender model used to design the parts, and an obj version of the assembly for those who use other modelling packages.
The pdf includes assembly instructions for when you are faced with a mountain of pieces and wondering how they go together. Each STL filename includes the number of times that piece needs to be printed. I have designed it so that no support is required.
You can find out more about the project on my website www.techmonkeybusiness.com - Railbike Project
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 36mm and sleeper length to 58mm to be compatible with this model.
Other than the motorbike model, things you will need are some 4mm dowel, some M4 machine screws with nuts and washers. For the model cables you will also need some wire. These extra items are described in the pdf - assembly guide.
