Fully assembled Mecanum Wheel

This is a fully assembled mecanum wheel.
You can try to scale the model but it's not recommended(the gap between the roller and the wheel is pretty tight).
Little support is formed under each rollers to prevent from deflection. You can easily cut them off after printing. And you might would need to do little sanding for the rollers.

A cross shape is extruded on the back of the wheel, which fits perfect with the Servo horn.
