I would like to introduce to you the sculpture »You & Me« from the »Scrappies« figurine family. It represents love, affection and mutual commitment - emotions that everyone values and never lose their significance.
The »Scrappies« are inspired by everything you can find in a scrapyard: old nuts and bolts, tin cans, pipes, coils, parts of ball bearings.
But they are actually manufactured in a totally different, novel »3D printing« process. Each of them is made in one piece from fine metal powders.
I had initially made the »You & Me« sculpture as a unique gift for our 30th wedding anniversary, but when Christiane placed the Scrappies on her office desk, her collegues loved them so much that we thought why not share it and make it available to others.
Therefore, and for a limited time, I am offering you my work here, outside of the traditional channels of exhibiting and selling art. Each figurine will be customized with your initials of choice. I will make and ship a unique »You & Me« sculpture for every supporter, be it one or many.
A smaller version of Triple Gear is available here. A baseplate and axle for using a motor to move the triple gear is available here. Also see 15 cm axle for Triple gear and 30 cm axle for Triple gear.
In this unusual mechanism three gears mesh together in pairs, and yet they can turn!

If you take three ordinary gears and put them together so that each gear meshes with the other two, then none of the gears can turn because neighbouring gears must turn in opposite directions. Triple gear avoids this problem by having the three "gears" arranged like linked rings - the gears then rotate along skew axes, and the opposite direction rule no longer applies (although see also Oskar van Deventer's Magic Gears for another possible solution).
This is joint work with Saul Schleimer. We were inspired by another of Oskar's designs, his Knotted Gear, which consists of two linked rings that gear with each other, and of course we wondered if it would be possible to do three linked rings!
Here is a paper on the mathematics behind the Triple gear, and how we designed it.
A note on materials: I have so far printed it in White Strong & Flexible only. It may arrive with the rings slightly fused together, but gently moving them back and forth will loosen them up, and the mechanism gets smoother with use. I'm not sure what effect the polishing process would have on the gearing mechanism, since it would polish the exposed gear teeth but not those which are meshed as it comes out of the printer. So I have disabled the polished material options. If you really want to try it, let me know. I also haven't tested any of the "frosted detail" materials, but I imagine that they should work fine. It isn't printable in the other "detail" materials because of cleaning problems.

Escher’s Playground - Reminiscent of the upside-down staircase paintings
by Escher, this 7x7x7 maze will soon have you forgetting which way is up
and down. The dimensions of this maze are 40mm by 40mm by 40mm and the
ball is 9mm in diameter.
Floating Labyrinth - The ball appears to float through an intricately
connected matrix. What appears to be open paths are mysteriously blocked
in this 6x6x6 maze. The dimensions of this maze are 31mm by 31mm by 31mm
and the ball is 8mm in diameter.
Zig Zag Zog - You will learn to zig zag
in three dimensions to solve this 5x5x5 maze, but watch out for the
pitfalls! The dimensions of this maze are 24mm by 24mm by 24mm and the
ball is 7mm in diameter.
Start
by pushing the ball into the spring loaded entrance ( it looks like a
backwards “J”). Tip the maze in different directions to roll the ball
along the paths through the maze. Don’t worry, if you make a wrong turn,
the ball will not fall out of the maze. If the ball runs into a dead-end
you can just roll the ball back the opposite way and try another path,
that’s all part of this fun brain game. When you reach the exit there is
a spring loaded button to press to release the ball from the maze. The
exit is in a corner of the 3D maze, where you will find a bar with the
little button sticking out from the side of the maze.
Each maze game come with the ball attached by a little chain link cage for shipping. This needs to be cut off and cut open with scissors and the ball will fall out. Note that each larger size maze comes with a larger ball. The balls can quickly and easily be colored with a highlighter or marker. Let the ball dry for a minute after applying then roll between clean white paper to remove excess color so it does not rub off on the maze. Paint for plastic models can also be used. The orange, green and black balls in the pictures were colored with highlighters or markers. Coloring the ball makes it easier to track in the Labyrinth maze.
