Basic Chassis for HOF Model Railways

This is a basic chassis for use with HOF scale model railways, it is compatible with standard HOF wheelsets, but can also be used with the printable wheelsets available here. The wheelsets don't always print reliably and the axle points sometimes break off when fitting, so always print some spares. The printed wheels don't run as well as the commercial ones, but are acceptable and can be seen in use here on my under construction layout "The Erratic Timber Supply Company" : https://youtu.be/kIy8GXE50x4?t=18
