SAR Garret GMAM Wheel

I was asked to produce a pattern for casting a 3 1/2" gauge SAR Garrett locomotive wheel for a friend. This was then 3d printed.

The wheel is to a scale of 1/12 full size, since South Africa has a 3' 6" gauge track.

I include the .stl file and also the Viacad Pro 9 file so you can fiddle with it and produce the driver wheel with different counterweight.
