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.

Found on an alien beach. Left by what creature?

A bigger model is here.

It's a little hypercube pendant! There is a slightly bigger one here.

A great way of expressing longer sentiments - up to 244 characters with a 8cm diameter. Your text will be repeated as many times as it will fit (with at least 0.5cm separation between each repetition). Width of the band is 1.1cm, and the text height is ~0.5cm.

For a cheaper option, see my Mobius Text Napkin Ring (http://www.shapeways.com/model/182784/mobius_text_napkin_ring.html?gid=ug28511).

NOTE: It's possible that this isn't printable in stainless steel, as the wall thicknesses are below the recommended limit of 3mm for this material.

It's a Cufflink! It's a button! It's both! And it holds your sleeve shut to boot! NOTE: These DO NOT come with thread in the holes (as you can see in the 3D file viewer). I did that after to add a little flair, and it's super easy to do. I'd be happy to help you with the process. For more on my designs or to contact me, visit www.prero.com. ALSO NOTE: The "GP" on the back has changed in the most recent file. Aside form that it's the same.

Here is a tower-like candelabra, which has a housing for an LED and coin battery (both supplied by purchaser). While the piece is lovely and interesting on its own, a shade is available, sold separately, in the shop to diffuse the light and provide more character.


Directions for assembly:

When you look at the housing where the coin battery slips in, you will notice that there are three supports that define this space. Two look the same, and one looks a little different. Let's call the one that looks different the "back support".

Get yourself an a standard 5mm LED. Any colour is good - your choice. For the brightest, I would recommend a super bright white or an ultra bright white. But for fun, know that blue and green LED's look very nice with the moon shade if you have bought it also :) Notice that one of the wires coming from the LED is longer. This is the "positive" wire.

Insert the wires of the LED down through the top hole in the candelabra, and wrap the "positive" wire around the "back support" taking care that it is placed so that it will only touch the battery at this place and no other.

Bend the other wire in a such a way that it will touch only the topside of the battery.

Get yourself a 2cm diameter, 3 volt coin battery. The ones I use are described by this code: CR2025. Insert this battery, negative side up, into the LED Candelabra housing.

Your Candelabra should immediately turn on nicely! Note that you can slide the battery slightly away from the back support and this will turn the light out.

If you have purchased the shade, this is very easy to twist on. Simply drop the shade down allowing its slots to slide over the three housing supports. Then twist the shade to secure it fits tightly.

Enjoy!

This modular mini planter system allows for the creation of a wide range of unique configurations. Water is shared through the system, flowing from the top planters into the bottom, saturating the soil of each plant along the way. These planters are perfect for air plants, succulents, or any small plant that requires little soil. Includes 10 planters, 3 double channel planters and 7 single channel planters. Individual planters are also available.

My second try on my yingyang soy-sauce bowl and I fell in love with it!!

While designing, it was important for me to focus on the meaning of asian numbers and modern design and to combine them with the Ying Yang.

I used 8 edges on the whole design. At the outside-top/bottem, inside, S-shape and at last on the two dots.

I hope you like it and enjoy your meal with it! :)

If you're interested in some bigger sizes, just mail me.


PS:
In the future there will be some more pictures of diffrent colours.
