Ami Drach and Dov Ganchrow recreate tools with 3D-printed handles, from Dezeen:

The hand-axe is a prehistoric teardrop-shaped stone tool that was intentionally chipped from both sides into a symmetrical form. It is likely to have been used as a “one size fits all” tool for a variety of purposes including skinning animals, preparing food and as a dagger for over 1.4 million years across Europe, Asia, Africa and North America.

For their Man Made series, Dov Ganchrow and the late Ami Drach sourced flints from an Israeli desert to recreate the early implement.

“The first stage of the project was one of hastened evolution and bleeding,” said Ganchrow. “Flint rocks of desirable size, shape and material quality were sourced from the Negev desert in southern Israel, while time was spent improving and understanding the skill of knapping – striking the flint with a softer stone to create controlled breakages, and chipping away flint flakes as the impact’s shock wave runs through the stone. Needless to say this is where the bleeding came in…”

Once shaped, the flint pieces were 3D-scanned so the handles could be designed to fit perfectly.

“The flint hand-axes were three-dimensionally scanned with the gracious help of Dr Leore Grosman’s digital lab at the Hebrew University, Jerusalem’s institute of Archaeology,” Ganchrow continued. “The digital hand-axe files then had handles custom-designed exemplifying various tool uses.”

By adding 3D-printed handles each designed only for a specific task, all other options for use were removed – transforming a general tool into very specialised one.

The team created nine handles, named from two to ten due to the numbering system used for archaeology lab’s original scans….

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! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. 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!
