wrench to scale...
Design Feature: The extra bit of steel is cut from the middle in the design. Even with thin edges, the wrench is usable as stainless steel has a high tensile strength. At the same time--- less volume = cost effective to 3d print and manufacture
Market Research:
Small size wrench grip needs a lot of force-torque a bolt for example. "As the moment arm (Force*distance) increases in length, the force applied is less to torque the bolt!" Scale the grip with any size wrench on Shapeways
