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!

Solid Marble like model. Full Color. Very accurate. 1.0 inch in diameter. View my store for a larger hollow version. This model has been a great selling item for me, and printed many times. Great for many different uses! This model has been orderd many time since I first uploaded it. I'm curious, what are people doing with it, send me a message or post a comment please, I'm dying to know! What other sizes would you like to see? I love the idea a customer left to use these as a Geocache item. Great idea!

A detailed full color model of each of the planets, gas giants, and major moons of the Solar system, to (logrithmic) scale.
This set includes the 20 largest objects in the solar system (bar the sun).
All surfaces are reproduced from NASA imaging.

For size reference, Jupiter is 25mm (1 inch) diameter, and Earth is 12.76mm (1/2 inch) diameter.
(A photograph of some of the planet models can be seen on th page for this subset of planets. Photos of this full set coming soon.)
This set is designed for use in orrery or other models of the solar system, and so to best present all planets while preserving scale, the scale has been compressed - a logrithmic scale instead of a linear scale. This means that if the model of a moon of Jupiter is larger than the model of Mercury but smaller than Mars, then you know that the real moon really is larger than Mercury and smaller than Mars, But the size diference is compressed - Jupiter, which is really more than ten times Earth's diameter, becomes only twice Earth's diameter, etc. This logrithmic scale allows all planets to be clearly visible together, while at the same time still indicating their sizes relative to each other.

The set contains all planets, a dwarf planet, and eleven moons:
[In order of appearance in the photo above, right to left]
Mercury
Venus
Earth
 - Moon / Luna
Mars
Jupiter
 - Ganymede
 - Callisto*
 - Io
 - Europa (attempt no landing there)
Saturn
 - rings of Saturn
 - Titan
 - Rhea*
 - Iapetus*
 - Dione*
Neptune
 - Tritan**
Uranus
 - Titania*
Pluto**

All objects have a 1.6mm (1/16th inch) hole at the south pole, for a brass axle (or a toothpick).

What color is a planet - is it color of its surface materials, or the colour of its atmosphere from space, or the color of the surface being colored by the atmosphere filtering light from the sun? The appearance in this set attempts to be that of the surface with moderate atmospheric influence, (with the gas giants depicted as the atmosphere and surface being the same thing). For example, this means that Venus depicts the features of its surface, but they are tinted somewhat by its atmosphere. Similarly, Earth and Titan show ground features, but some areas are tinted and obscured by atmosphere.

In areas where the model surface is more detailed than the most detailed NASA photography (such as Pluto), the overall surface appearance conforms to what is known, but finer textural details are speculative. (Or, if there is an atmosphere, it is shown as particularly thick and opaque over the unmapped area.)

*Due to hard limitations of the Shapeways production, these minor moons are sharing the same surface map. They were chosen because they have a similar surface, and/or their surface is largely unknown.
**For the same reason, Pluto and Triton, which have a similar icy surface and not much photographic detail known, also share their surface map.
(The alternative was to not include those moons)

Magic Gears is a paradoxical set of three identical gears that can both mesh in the regular way and all in the same direction. It was inspired by this YouTube video by Jacques Maurel. Maurel writes: "The paradoxical 2 teeth gear set is used in the 'Mercier differential' (using the torque transfer technology) Patented in 1988 by Renault". Oskar's addition to the work is making Chevron Gears as invented by Andre Citroen. This way the three gears become identical and they can both mesh classically and paradoxically.

I have performed this Magic Gears "trick" to several friends, family and colleagues. I get two types of reactions: "wow" and "so what". Apparently, there exist people who are not aware how gears are supposed to mesh :-).

The set is delivered as a DIY kit. You will have to add five M3x60 bolts yourself.

This fully posable crayfish has moving joints - antennae, eyes, legs, claws, and tail - printed in place. It is inspired by the handmade articulated Japanese sculptures of insects and crustaceans, 'jizai okimono' which were popular in the Meiji era.

The default material is white nylon sintered plastic, which is relatively tough and can be painted with acrylic paints.

Looney Gears is a strange eccentric planetary gearing system. Whereas normal planetary gear systems are symmetrical, this one has no symmetry whatsoever.

This particular set of gears was the result of a challenge by Oskar to Andreas Röver in 2006. Andreas found this nice set of all-primary-numbers gears which is about 0.01% exact.

When Oskar made the Looney Gears, he made the conjecture that there do not exist exact solutions for this type of eccentric planetary gear systems. After seeing Oskar's video of Looney Gears, Bill Somsky proved that there are actually huge numbers of exact solutions for Looney Gears. These exact solutions are now called "Somsky gears". Somsky's discovery and proof showed that Oskar's conjecture (that there are no exact solutions) is wrong.

Please contact Oskar directly if you are interested in obtaining a fully colored and assembled sample of this puzzling object.

A small dish suitable for a dipping sauce, mints, pins, etc. This would make a wonderful wedding favor, filled with candy and wrapped in gauze. Beautiful in glazed ceramic, or try it in full-color sandstone for something even more unique. (Full-color sandstone should be given a clear coating to protect the surface and bring out the colors - try Pledge acrylic floor polish, for instance.) Designed with ceramics in mind (they are food-safe), but printable in a wide variety of materials. Contact me if you would like some variation on this (e.g. bigger, thinner, with more or less twist, or different coloring).

Before May 18, 1980, Mt. St. Helens, a stratovolcano in southern Washington State, looked like many of the other high peaks in the Cascade Volcanic Arc: conical, steep, and snow-covered. But after that day's eruption, which moved nearly a cubic mile of debris from the peak down to the Toutle River and Spirit Lake, the landscape was grey and dead for miles around. The mountain lost 1300' of elevation, and the top became a crater a mile wide. The area was made a U.S. National Monument in 1982, hikers were allowed back on the summit in 1986. Though forests were knocked down and covered with grey ash and pumice, vegetation has made a surprising and resilient recovery, making the valley glow green in spring.

This model shows the post-eruption terrain, with its unmistakable open-sided crater and lava dome. In addition, hikers will recognize the top portion of Monitor Ridge and Shoestring Glacier. Other features on this model are Crescent Ridge and the head of the South Fork of the Toutle River to the West, part of Studebaker Ridge to the North, and Windy Pass to the Northeast. Simply put, two-dimensional maps cannot convey the magnitude of the eruption, but holding this piece in your hands, you just might begin to understand.

Model scale is 1:46700
Model covers an area approximately 4.4 by 4.4 miles
Altitudes covered: 3250' to 8337'

TinyMtn models look best in the default "White Strong and Flexible" material, which is also the least expensive material. When you receive the model, there may still be Nylon dust on it from the printing process. Use either an airbrush, canned dust blower, or a soft old toothbrush to remove this dust. Do not get the "White Strong and Flexible" material wet, and don't prime it or use any oil-based paints on it. You can safely seal it with Polycrylic or a similar water-based clear spray sealant. Read more about this popular material here.

The "Frosted Detail" material will show more detail, but is semi-transparent and has an uneven surface texture when unpainted (due to the orientation of the model when Shapeways prints it). It may show up feeling a little greasy and with small crystals in crevasses. Clean those off by soaking the model in warm (but not hot) soapy water and brushing with an old toothbrush. To get the surface to an even matte finish, spray with a few light coats of sandable primer (white automotive primer works), and then do a baking soda grit-blast.

These models have been optimized for the above materials, and are not offered in other materials for strength or cost reasons. If you need one in another material, please contact us and we'll try to accommodate your request.

Mt. Rainier's 14,417-foot peak is visible for nearly one hundred miles on a good day, and is an iconic feature of the horizon in Western Washington. A strato-volcano, Mt. Rainier's present cone is one half-million years old and covered with glaciers that amount to nearly one cubic mile of ice. Though it last erupted in 1854. Rainier is still potentially active, and because of its proximity to the densely-settled Seattle-Tacoma area and the massive amount of ice that would be melted during an eruption, it poses more risk than any other volcano in the US.

This model showcases Rainier's summit and steep cone, and because we used the latest USGS high-resolution data, minor features as little as 100' wide are modeled. Little Tahoma dominates the Eastern slope, the summit crater is obvious, and crevasses in the mountain's major glaciers are even visible. If you can't see Rainier every day, or if you can, but only from one angle, put this mountain on your desk or coffee table and enjoy it whenever you like.

This model was created with an algorithm that takes a bitmap file as input and outputs a mesh full of holes. The size of the holes match the intensity of the pixels in the input file.
