Simultaneous mechanical motion is found in camera apertures, foldable steamer baskets, and other delightful objects. The motion of all parts is connected through overlaps, gears, or linkages. Pull on one part and everything moves together. The unique feature of the Venn Puzzle is that it achieves this simultaneous motion without a larger constraining system. It's simply the 3 parts interacting with themselves that create this mesmerizing movement. A puzzle like this doesn't do anything. It won't take a photo or help steam your vegetables. Nevertheless, we still care about "useless" objects like these. We spend a lot of time working with beautiful mechanisms and sometimes it's nice to showcase these discoveries in the most pure and satisfying way possible. We call this one the Venn Puzzle!

Chroma Scissors A cutting edge classic. Available in Primary and Black editions.

Same cut, new form. When we first designed the Ripple Bottle Opener, we only had access to a 2D mill. We had to find a clever way to make the most of it. Although we have more resources now, we still produce this object using the same manufacturing method. It's an elegant way to create a beautiful form.

The reason why your trash can tapers. Most injection-molded objects have a slight taper for easy removal from their mold. This taper is called a draft angle. You see this design feature in everything from trash cans to phone charging blocks. However, some forms can't be helped by a taper. A plastic screw cap has threads that prevent it from being pulled out of its mold, no matter the draft angle. So, how do you make a mold for a screw cap that allows the part to be removed without damage? Let us know what you think in the comments.

Unleash your potential. The swoop-down lid on our Summit Card Case doesn't intersect the internal volume, allowing you to use every cubic inch for whatever you want. So, what would you put in here?

Being sharp doesn't cut it. You also need to have the correct blade alignment. When the blades cross each other without a gap, the paper has nowhere to escape and must tear apart. Only once the alignment is right does the sharpness of the blades come in handy. One is nothing without the other. That's why our Chroma Scissors (and all good scissors) have both.

Joy prevails.
