This Swiss Mechanical Watch Was Made With a 3D Printer

The technology behind the mechanical watch hasn’t changed too drastically over the centuries, but this version has an unmistakably modern twist. To build his new watch, Swiss engineer Christoph Laimer put his design into a 3D printer.

Other than the metal pins holding it all together, every component of Laimer’s mechanical watch, down to its flexible spring, is made from 3D-printed plastic. The watch is only capable of running for 30 minutes at a time, and when it is working it isn’t terribly accurate. Even if these factors weren’t an issue, the “watch” would still be too large and bulky to fit onto your wrist or in your pocket. That being said, the project is still a remarkable first step for watchmakers hoping to make their craftsmanship accessible to a wider audience. 

The most exciting part about Laimer’s creation is that anyone with a 3D printer can make their own at home. He’s made his source files available on Autodesk’s 3D printing hub, where they can be downloaded for free. Engineering enthusiasts are welcome to take a swing at improving upon his original design, or they can simply use it as learning tool to explore the intricacies of Swiss watchmaking. You can see Laimer’s final product in action in the video above.

26 Facts About LEGO Bricks

Since it first added plastic, interlocking bricks to its lineup, the Danish toy company LEGO (from the words Leg Godt for “play well”) has inspired builders of all ages to bring their most imaginative designs to life. Sets have ranged in size from scenes that can be assembled in a few minutes to 5000-piece behemoths depicting famous landmarks. And tinkerers aren’t limited to the sets they find in stores. One of the largest LEGO creations was a life-sized home in the UK that required 3.2 million tiny bricks to construct.

In this episode of the List Show, John Green lays out 26 playful facts about one of the world’s most beloved toy brands.

Of Buckeyes and Butternuts: 29 States With Weird Nicknames for Their Residents

Tracing a word’s origin and evolution can yield fascinating historical insights—and the weird nicknames used in some states to describe their residents are no exception. In the Mental Floss video above, host John Green explains the probable etymologies of 29 monikers that describe inhabitants of certain states across the country.

Some of these nicknames, like “Hoosiers” and “Arkies” (which denote residents of Indiana and Arkansas, respectively) may have slightly offensive connotations, while others—including "Buckeyes," "Jayhawks," "Butternuts," and "Tar Heels"—evoke the military histories of Ohio, Kansas, Tennessee, and North Carolina. And a few, like “Muskrats” and “Sourdoughs,” are even inspired by early foods eaten in Delaware and Alaska. ("Goober-grabber" sounds goofier, but it at least refers to peanuts, which are a common crop in Georgia, as well as North Carolina and Arkansas.)

Learn more fascinating facts about states' nicknames for their residents by watching the video above.
