There’s no need to buy an electric screwdriver, just 3D print your own!
What do you do when you need to attach 400-500 screws for an upcoming project? If you’re “Progress Thailand” you simply create one yourself using a 9g micro servo modded for continuous rotation, an Arduino Nano, and some 3D printing!
The build uses a small thumb joystick for proportional control, and can accommodate a small hand driver in addition to a bit by itself. Impressively, a functional prototype of the tool was produced in a single day, with the final(?) version appearing a couple of days later.
Hand and power tools are cheap, reliable, and easily accessible. But their production is still done in large centralized factories. 3D printing technology and cheap, open source electronics continue to improve bringing the decentralization of manufacturing one step closer.
We are experimenting with different designs to see how close current 3D printing technology can bring us to production-quality tools you can buy in the store. We’re also experimenting to see what modifications we can make to store-bought tools to enhance and customize their use.
While they note that the project isn’t meant to replace commercial screwdrivers at this point, it looks like a fun project with all the needed files available here to modify and improve things to your specifications!
