This product consists of a set of four (4) disc N scale wheels intended for use with VR N Scale Model products. These wheels are being provided as a separate product so as to reduce the cost of other model products (as there is an additional cost for models with more parts) and provide customers with the option to substitute these parts with metal wheels from providers such as Intermountain or Fox Valley Models.
For those with the ability to print their own STL files, these wheels are also made available on
Thingiverse (although those offered on Shapeways are connected on a sprue to reduce print prices).
