Allen Key Socket Adapter

Device to allow using regular allen wrenches on a 3/8" drive socket wrench/T-handle. This was done primarily as a thought and design exercise, as long-reach allen 3/8" drive wrenches are commonly available. As of this time, only a 2.5mm adapter is completed, as it was the only one I needed at the time. Will update with more in the future. Secures together using standard M3 screws and nuts. Size is rather large, to provide strength when turning higher torque loads and for turning by hand.
