The OpenBuilds Solid V Wheel is a strong wheel that resists deflection due to it's solid nature.
This wheel style was produced for two reasons. - First is for builds where heavier loads are required and less compression in the delrin is desired. Many of these wheels could be added to a gantry to allow an even distribution of the load across them. - Second is for improved performance of the belt and pinion system to give the belt a flat surface to ride on.
