Ratchet screwdriver with torque control #3DThursday #3DPrinting

22steve22 shares:

I designed this ratchet screwdriver to be adaptable for all 6-Kant 1/4 of inch bits.
The bit rotation is locked while unscrewing and for screwing the spring provides a torque control.
The maximum torque depends on the spring stiffness and on the length of the spacer.

To adjust the maximum torque for screwing I also included a M5 nut in the back of the handle that allows to increase the torque screwing on the back of the screwdriver a M5 bolt (This part is optional).

The ratchet is a single piece that have to be printed twice: one for the head of the screwdriver (have to be inserted in it) and one moving with the spring.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
