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 third public evolution of the Animaris Geneticus Parvus. #7 has evolved legs, with pointy feet instead of flat. Featuring a fully working Theo Jansen mechanism as used in his work "the Rhinoceros".
Also see our new Propeller Propulsion add-on, to have your Strandbeest walk autonomously!
The mechanism is printed assembled, and will work without further assembly right after birth from the printer.
A few tips to consider:
- After birth there might be a little powder left in some joints, or it might not go supersmooth. This will fix itself after the animal has a little bit of practice!
- Some surfaces work better than others. The legs require a little friction, and a flat surface. So for example: A rough table or floor, thin flat carpeting, or a thin rubber sheet. It will slip on a too smooth surface.
- The best way to push it is by its nameplate. Do not push down, but forward.
- The beest is light, but quite strong. It can actually be dropped without breaking. It is not a "toy" however, and not suitable for children. The 3D printer material is easy to stain so clean hands are advised.

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.

The nocturnal (or nocturlabe) is a very old instrument for telling time at night by measuring the stars. While concept is ancient, this design is all original. It is fully functional (all dials move properly) and meant to be worn as a pendant. This is now available for sale, as it has been tested and works nicely.
How to Use the Nocturnal:
The top of the nocturnal is where you see a bit of a ring around a spike. This ring can be strung with a chain and makes it possible to wear the nocturnal as a pendant. When reading the nocturnal, this end of the piece should always be up.
Your first step is to set the outermost dial on the date. The months are shown as letters, with January and December at the top, and the progression of the months running *counterclockwise*. Note that the exact position of the letter actually marks the middle of that month. Look closer at the piece and you will see the line that separates the months between the letters.
Now, hold your nocturnal up to the starry night sky, making sure that the date is still properly set. Locate the North Star centred in the hole in the middle of the Nocturnal. Then use the central dial (the one that looks like a pointer) to point to the two stars at the end of the bowl of the *big* dipper.
Once you have this all set. Look closer at the pointer and you will see that within the pointer is an eliptical ring and within this is a smaller pointer. This smaller pointer points to a roman numeral, which shows you the time.
Note again, that the roman numeral is centred on the middle of the hour. So, if the little pointer points in the centre of the numeral, it is in fact half past.
So now you can tell time at night without a powered time piece. This is great for night owls, vampires, and those who appreciate a gothic or steampunk look.

Skyrim pendant
I made a pendant inspired from the The Imperial Symbol of the game Elder Scrolls V: Skyrim. I hope people who love this game also love this pendant. On the top of the wings are two holes, so you can wear it like a pendant. The pendant is double sided, both sides look the same. The picture shows the wrong way ;-0
I already have pictures of the pendant in stainless steel pictures in stainless steel
Also check out my Skyrim 'Dragonborn' ring Skyrim 'Dragonborn' ring.
The pendant is inspired on the game Elder Scrolls V Skyrim. The rights and intellectual property of the game belongs to Bethesda Softworks, which did a great job on creating the Elder Scrolls series.

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.

Make your own slide-on macro lens for the iPhone 4 or 4S. I designed this for my iPhone 4 when I couldn't find the image quality I wanted for less than $60.
Print this model and then buy the glass lens for $4 from Surplus Shed (http://www.surplusshed.com/). The Surplus Shed part number is L4471. For some reason the search box on the Surplus Shed home page does not work with part numbers. To get to L4471, use the "Lens Finder". In the Lens Finder type:

Lens Type: PCX, Plano Convex
Diameter: 12mm to 12mm
Focal length: 51mm to 51mm
It will get you to L4471
The lens fits in a recess in the model and is held in place with a few tiny drops of Superglue. If you get any glue on the lens it can cleaned off with nail polish remover or acetone. The lens is plano-convex (one side is flat). When inserted in the holder, the flat side of the lens faces the phone.
Note that the lens fits pretty snugly into the opening. Try fitting the lens before applying any glue. A good technique is, with the lens holder laying face-down on a table, lay the lens in position, and then push it into the recess by poking the lens with the eraser-end of a pencil. Once you know the lens fits cleanly, push it back out and put two tiny drops of superglue on opposite edges of the opening. I use a toothpick to apply the glue because squeezing the superglue directly out of the tube risks putting on too much. Then push the lens back in the same way as in the test fit.
The object pictures in the photo gallery (dime, ruler, and watch) are unedited and uncropped shots directly from my iPhone4.
This model will not slide over iPhone cases.

Dodecahedral sibling of Gyro the Cube.
Same principle, more faces, more rings and more fun ;-)
Made of five nested dodecahedra, each one is limited to rotate about it's own axis.
This is the 6.5cm / 2.5" version, see the Gyro the Forms
Experimental corner stand available here
Instructions
For tighter clearances it is printed with the hinges out of place. So this model needs a little manual assembly. Each element has two "knobs" which need to be "clicked" into the corresponding "clamps" in the parent element.
It's easiest to start with the inner one and then continue outwards.
And then... rotate away !

Over 100 latches ordered in the last 12 months!
Replacement stainless-steel upgrade / repair latch part for the Panasonic SD253 seed / nut dispenser (see pictures).
Easy to fit with a cross head screwdriver.
1. Remove dispenser from lid (it just pops out).
2. Wash?
3. Remove old latch part by undoing the two cross head screws and lifting out U bracket.
4. Rescue the small spring which keeps the latch engaged.
5. This spring has one end that narrows down slightly. Hold the very end of this with tweezers or needle point pliers and then wrap the spring onto the cross (a tooth pick or a match end is handy for this).
6. Place new latch in position, add bracket and resecure with the two screws.
7. Make bread.
Any help / comments please get in touch.

Phamora Ceramics!
Is inside out? Or is it not? Perhaps both?
This is an Amphora from another space-time.
An ancient object which we knew had to exist.
And after years of excavation in other dimensions we finally found it!
A very exotic vase with a unique near-impossible shape, suitable for use with dry flowers and striking enough to stand alone.
Theoretically it can also hold water in the toroidal bottom part, read practical details below.
Very suitable as a wedding gift to symbolize love and infinity.
The number eight (or sideways infinity) plays an important role in this piece,
both in the number of arms and the cross-section of this model.
Notes:
To improve print quality and after some deliberation with production, this model has been slightly updated on August 24th 2012; The arms have been thickened and the holes enlarged to improve strength and glazing.
Still I recommend not to put a lot of stress on the handles.
Refer to rendered images for the latest version. I will update photo's asap.
The bottom it stands on, is unglazed, which is invisible during normal display.
All clearly visible parts will be fully glazed, but there is a chance some parts on in the inside might not, which may compromise it's ability to hold water.
While production does their absolute best and all recent prints turned out perfectly glazed and hold water, due to the complexities involved, there is no 100% guarantee for to be absolutely watertight.

These filigree earrings look delicate almost like lace, yet are flexible and very resilient and should last you a life time assuming a monkey doesn't eat them. They are so light that you wouldn't even know you are wearing them.
Here they are shown in the "White Strong & Flexible" material, but are also available in other colors as well as silver. They are each about 1.5 inches long and .75 inch wide.
