U.S. Penny Screwdriver for Sewing Machines #3DPrinting #3DThursday

U S Penny Screwdriver for Sewing Machines by elhalpern Thingiverse

elhalpern shared this project on Thingiverse!

Necessity is the mother of invention !

Working on older sewing machines is always annoying when I have to remove the slot-head screws on the thread plate near the foot.

Manufacturers are kind enough to use screw that can be driven with a coin, but the space you need to work in is too tight to precisely hold & twist a coin. Human thumb and index fingers are awkward in this space around the foot of a sewing machine.

This design solves the problem by transforming a U.S. Penny into a screw-driver that works ergonomically allowing precise control of the coin, and the ability to spin the coin and a targeted screw without damaging the slot of the screw.

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!


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.
