Random 3D Prints

I printed a random things recently. The red keys on the right are for getting the all of the toothpaste out of a tube - you just twist up the tube on the key as you go. The print on the right is a small puzzle box I designed on paper years ago. I found it in an old notebook and decided to try to model in SketchUp and print it. Both of the green keys ride in dovetail channels, so they can both slide along their respective axis. A channel along the bottom of the smaller key engages with a pin on the blue box's body. You have to slide the two green keys in the correct pattern to move the pin through the channel until the keys can be freed and you can get access to the interior of the box. Maybe sometime soon I can make a short video showing how the box opens.
