About this 3D model

Interlocking curbs for RC car tracks. I made if for my backyard track. There are three different radiuses. I suggest tent plugs to hold in place for off road tracks. Curb01 is 2200mm radius Curb02 is 500 mm radius Curb03 is 200 mm radius and is the smallest Curb04 is a 160 mm long straight section Curb05 is a 100 mm long straight section Center01 is a center cup for the smallest curbs.
