Accused of being fake, witchcraft and simply impossible..
This kinetic sculpture is inspired by the unlimited freedom of 3d printing,
it wobbles and turns with a slight movement of the hand.
Now give it a good spin or puff of air and it erupts in erratic and wild behavior.

This is the 5cm / 2" version, see the Gyro the Forms section for other shapes and sizes.
Corner stand available separately, or get the complete set below!

NEW!
Now also available as a pendant/keyfob!
In both Extra small and Small

Instructions
It is composed of four concentric cubes, each one spinning around a different axis.
The model needs some minor assembly:
Each inner cube has two knobs which need to be placed into the corresponding clamps in the parent cube. It's easiest to start with the inner most and continue outward.
And then... spin it away !

Notes
Do not be alarmed if your cube will not run smoothly at first!
Because of minor variations as a result of the printing process,
some need to wear in a little but will loosen up very quickly.
In the example video I am blowing on it to make it move, it's that smooth.

Be a little careful with (the assembly of) the Alumide version as this material is slightly less flexible/robust than the Strong & Flexible materials.

Get a complete set.
A default set consists of an Alumide Gyro the Cube and a White stand, you can change the materials in your cart later. +

The filigree design over the skull symbolizes ever growing renewal over the ghost of the past. This is the original design as featured on Kickstarter. It became their #1 most funded sculpture project of all time. Small is pictured sitting in the hand. See pic of all 3 sizes together for comparison.

This is a mobius strip of Level 1 or Super Mario Bros. The whole level is wrapped around itself in a single surface, and poor Mario begins and ends at the same spot every time :(

All the elements from the level are there: every mushroom, turtle, cloud and star. They are all carved out of the surface at different heights, which looks fantastic when you have a light coming from the side, and each block casts a shadow.

It's a great piece to have on your desk, or to hang from a string to let it spin around.

A theorem walks into a bar...
The Klein Bottle is a mathematical joke: a surface with only one side. This one feels just right in your hand and opens bottles with ease and style. Built to last in steel, it's the perfect touch for any math fan's kitchen.

Yes, it really works!

Klein not-a-bottle-opener is here.

There are six regular convex polytopes in 4D, which are analogous to the five Platonic solids in 3D. This is the fifth, the hyperdodecahedron, a remarkably beautiful object brought to my attention by George Hart.

Here it's shown in a Schlegel diagram so you can see all 120 dodecahedral cells, though most are transformed by perspective: in this projection, the only regular dodecahedra are the biggest one on the outside and the tiniest one at the center.

A bigger model is here.

A Sierpinski tetrahedron, the 3D version of the Sierpinski triangle, stage 5 I think. There are 4096 of the smallest tetrahedrons. The model has 499994 faces.

Update:
The edges are now almost 18 cm (7 in) long and it stands about 14.5 cm (5.7 in) high.

The model has been updated because the smallest struts were a bit too small to be printed. So it's now 1.5 times bigger in all directions.

The pictures are of the previous smaller version, the new version has been ordered successfully a number of times in WSF.

I created the model using POVray and MeshLab.
