This bogie set is designed to be compatible with the model railway gauge I am using for my [stop motion mine trolley](https://www.youmagine.com/designs/mine-trolley-for-stop-motion) and [mine truck](https://www.youmagine.com/designs/mine-truck-v3). At this scale the track gauge is 36mm between the inside edges of the rails. These bogie sets will be used in a number of other projects but I felt that as a standalone project they might be useful to others. The overall dimensions of a single bogie are; 62mm wide, 80mm long, and 25mm high. I have a 1:24 scale version of this [here](https://www.youmagine.com/designs/1-24-scale-powered-bogie-set). The details were designed based on a large number of powered bogies for railcars, and diesel locomotives. I wanted to create a bogie set that looked plausible. I was also keen for the arrangement to give the impression of being an electrical drive. The models here include the *Blender* model. I created it in Blender 2.58 and so you will find there are no problems with using this model in any of the 2.5+ versions of Blender. Extra things you will need are; * some Ø4mm rod of some sort. * An M4 nut and bolt. For the axles I use wooden dowel, but anything will do. The axle lengths are about 54mm long. The nut needs to be installed in the top cross spar early in the assembly. I would suggest gluing it into the socket. No support is required. There are some break-off bits on a couple of the motor components. The filenames include the number of times you will need to print of each bit.
