I originally designed this 3D printable finger wrench set for dinghy boating, where minimizing size and weight is crucial. It might be useful for other applications like biking, camping, kayaking etc. It allows for significant torque by hand, and even more can be achieved by sliding an axle through its 8mm holes.

For durability, choose materials suitable for your needs. While PLA might prove too soft, leading to easy breakage, PC and PA-CF are robust choices for more demanding tasks. Also, ensure you configure an adequate number of perimeters to enhance the rigidity of the wrenches."
