An espresso cup specially designed with fins, to ensure the successful deployment of your rocket fuel. All systems are go! Paraboloid bowl holds approximately 1.5 fl oz. or 45 mL. (Note that I previously claimed the cup held 60 mL. While my 3D modelling software still reports that as the internal volume, some combination of the printing process and glazing is robbing me of internal volume. Contact me if you'd be interested in a larger, more expensive 60 mL cup.)
After receiving feedback from Shapeways, I've created a slightly revised model for the cup. I'm told that this model will be easier to print and glaze, leading to a more reliable product. The changes are minor -- it's a little wider, a little heavier, and has more rounding on edges that were previously sharp (a 3D rendering shows the differences above).
Update (April 13th, 2013): The cup has had a great run on Shapeways, and I deeply appreciate the attention and positive feedback it has received. The bad news is that I've got to stop offering it for sale here. The good news is that the cup is now available commercially! It's being manufactured by Fred and Friends, sold under the name "Blast Off! Espresso Cup Set". It's already available for purchase online (perpetualkid.com, thinkgeek.com), and I'm sure you'll be able to find it in your favourite housewares store soon.
If you'd prefer a right hand spiral, please see; http://www.shapeways.com/model/169011
NOTE:
Shapeways have decided that this model is unprintable with the ball enclosed.
This model will take a 6mm steel ball which can be fitted by gently forcing open the spiral... see video.
A 5mm ball is available here; http://www.shapeways.com/model/172759 or simply use a suitable (4.5mm-6mm) ball bearing.
If you want to get a polished and fully functional QR code pendant, set the delivery address to my one (I will provide it by a private message). I need to get the product first to finish it and then send to you.
This QR code tag can contain any encoded message that you wish (min. 18, max. 32 characters). If you want to make it a functional url tag, you need to include "http://" part!!!
The QR codes are now used in many spheres of life. They can contain numbers and letters, so you can encode any kind of text information, be it address, phone number, message, name, web link, etc.
Most of the modern mobile phones (and apple iphone was one of the first to feature this technology) can decode the QR codes, making QR-coding a funny, easy and peculiar way to say something.
You can use this tag as a keychain or as a pendant.
Also, check out this colored plastic tag!! It's cheaper, it's bigger and it's colored! :)
