Hackaday highlights the work of Ben who has developed a wonderful concept – making inexpensive wrenches with printed circuit boards. They won’t replace quality tools, but for light use, they are much better than 3D printed models and are 0nly 9 cents to make in quantity.
Since Ben has been kind enough to release his design under the MIT license, you’re free to spin up some of these wrenches either for your own kits or just to toss in the tool bag for emergencies. We’d love to see somebody adapt the design for additional sizes of nuts, or maybe figure out some way to nest them to sneak out a couple extra wrenches per board.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
