Wheel set to expand your TeacherGeek ideas.
The TeacherGeek Wheel/Hubs are uniquely designed for multiple purposes. When used as wheels for vehicles TeacherGeek Tires may be added for additional traction. Splined holes securely hold dowel axles for a non-slip fit. Combined in pairs they become hubs for turbines with the ability to securely hold 2, 3 or 6 blades that can easily be interchanged.
