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. +

Important notice: a lot of people have been very happy with this product, but, as can be read in some of the comments below, it's clear that this design is right on the edge of what Shapeways can produce to the right quality at this moment. If you buy it, there's a risk of having a less then perfect fit, colors can be different from what you see on the screen, and, depending on how you use your phone as well as the tolerances of the case, it has been reported that the polyamide material can give a sort of polishing/scratching effect on the metal rim of the phone (you can find descriptions online of how to remove these kind of blemishes, but it may still be annoying).
Shapeways has, in my experience, been very good with customer service on this item, so they'll be happy to either return your money or provide a new product if you would be one of the unlucky ones; but it's up to you if you want to run the risk that you may have to go through this process.

Essential protection for iPhone 4S and iPhone 4

Even though 4-4 may be the worlds lightest and smallest iPhone 4 case, it still provides great protection to the vulnerable edges of the iPhones' front and back covers - while all controls and connections remain accessible. Its slightly protruding profile helps prevent protect the glass when laying your phone down; using 4-4 can also help to avoid signal loss problems.

This bumper-style case may be combined with commercially available screen protectors. 4-4 is manufactured from tough and durable 3d printed polyamide; it has a slightly textured surface that gives you great grip on your phone. Available in white, black and limited edition colors - note that in white, the 3d printed material may get dirty more quickly - but you can (seriously!) dishwash this product, so that shouldn't be too much of a problem. The 4-4 case is designed to have a tight fit around for iPhone. To put the iPhone in the case, or take it out, start at one of the bottom corners, where there are no buttons. Colors in the images above are for reference only; please check under 'select material' to get the most up-to-date preview of currently available product colors. Product is shipped in basic Shapeways packaging.

4-4 fits the GSM and CDMA/Verizon versions of iPhone 4, as well as the new iPhone 4S.

A two pack of 4-4's in the same color is available at reduced prices here.

You can have a look at all the products in my shop here. Consider buying 4-4 together with The Wrap, a handy cable winder for the European iPhone charger.

A replica of Cobb's totem from the film "Inception". As a below review has noted, and from my own version, the top works very well, and spins upwards of 90 seconds before toppling. You just might be in a dream.

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.

Update: I am currently working on an updated version, which is more robust and uses a more conventional 3-axis design (one servo per axis). I will leave this model available for spare parts. The new model is currently being tested and should be available soon.

 This is a 3-axis gyro-stabilsation gimbal for the GoPro HD Hero camera. Intended use is for aerial video and first-person view (FPV) flying.  
(Picture shows all the parts - camera is not included, and this is model here is only the back cage. Check the 3D model to see it. For the complete kit you have to order the back cage, the front lid, the servo cage and the mounting arm.  You will also need 3x MKS470 servos, and a 16mm x 8mm ball bearing, not shown)

Video demonstration:

Assembly and servo test

Preliminary Gyro stabilisation test 




Current status: 
This is still work in progress - the current version has been slightly improved from the version in the video (I strengthened some of the elastic parts and improved the balancing). The gyro control board is my own design and currently not available yet. I will post an update once it is. The IMU is my design as well, and is available here.

You are welcome to order this design now, but be aware that it's still somewhat "beta". Whatever you do with it is entirely your own risk and responsibility, I unfortunately cannot make any claims towards its usefulness, stability or safety...

I would recommend, before you put this on a flying contraption, consider using a safety string to attach the camera to the plane somehow. GoPro cameras are very robust inside their waterproof case, but not quite so robust without that protection. They don't like crashing into the ground (and trust me, I know - as is probably obvious from the picture of my camera... in all fairness, it did mostly survive...)
Assembly instructions

For the complete kit you have to order the back cage, the front lid, the servo cage and the mounting arm.  The bearing at the top is a 16mm outer, 8mm inner diameter ball bearing, available from many places. Hobbyking sells those as well.
I will possibly modify the mounting bracket in the future and also offer one with a smaller bearing... this one is total overkill! :)

The servos that will fit are the MKS DS470 (available e.g. from Hobbyking). They do have a little play, but they are very smooth and by far the fastest servo I've seen in that size and price class. I'm still on the lookout for different servos that might be a bit smoother.

Assembly:

1) Press the servos onto the mounting bracket and the flexible arms of the back cage.  What works quite well is to carefully push it on just a little (best to put the printed piece onto a flat surface, and gently push the servo in just a bit to align). Then use a screw (maybe with a washer to spread the force), and slowly pull the arm onto the crown. You only have to do that once, it'll be a tight, smooth fit afterwards.
Remove the servos again after this step.

2) Mount the 3 servos on the servo mounting frame.  Start with the yaw servo (the vertical one in the middle).The yaw servo crown has to face downwards (might be a bit fiddly). Make sure the crown of the yaw servo is aligned with the little stub axle on the opposite side. The two roll/pitch servos have to be inserted so that the crown faces the camera (towards the flat side of the mounting arm).

3) Press the mounting bracket onto the yaw servo crown, and put in the screw to hold it in place. On the opposite side, press in the 16mm/8mm ball bearing.

4) Carefully push the disk-shaped closure knob into the cylinder at the top of the camera back cage. You might need to rotate it a bit to ease it into place

5) Push the flexible arms of the back cage onto the two roll/pitch servos, and fix with screws.




-- Update: Seems the MKS has too much gain for the yaw axis, and tends to oscillate a bit with all that weight swinging around. They are fine for the Pitch/Roll arms. I'm still looking for a small servo with high speed, smoothness and no (or little) play... Suggestions are of course welcome!!

-- The servos are still a very tight fit into the control arms and the bracket. I already made it a bit larger, but still not enough. What works quite well is to carefully push it on just a little (best to put the arms onto a flat surface, and gently push the servo in just a bit to align). Then use a screw (maybe with a washer to spread the force), and slowly pull the arm onto the crown. You only have to do that once, it'll be a tight, smooth fit afterwards.
