If M.C. Escher had owned fidget toys, he would have worn "One ring to rule the ball" as a pendant. A single, continuous line contains a small ball that makes orbit after mesmerizing orbit but cannot escape, always held down in four directions. Available in solid, durable stainless steel with optional antique bronze and gold plated finishes to fit any context, "One ring to rule the ball" now also includes a free rubber necklace so that you can confuse your mind any time the fancy strikes you! One customer echoes many others in saying, "I couldn't put it down. This thing is just too fun!"

Purchases by those gracious customers have now paid for the design time on this piece so it is available on a pay-what-you-want basis. Ordering from this page contributes 5$ towards continuing work such as the new, even more impossible "One ring to pwn the ball" (just released October 18th!) which can be found at http://www.shapeways.com/model/145172/one_ring_to_pwn_the_ball.html and the open-source "Ultimate Desk Toy" at http://www.shapeways.com/model/109166/ultimate_desk_toy.html .

Update: Dremelfuge is now provisionally available in the "Strong and Flexible" material, after some basic testing. No guarantee of safety is given, as always. The "Strong & Flexible" material Dremelfuge creates more vibration in use, which may indicate less stability than the "Grey Robust" (ABS) material. Caveat Emptor: As always, Dremelfuge is sold as an ornament, and any use as a tool is a risk entirely taken by the purchaser/user. I accept no responsibility for the safety of Dremelfuge.

DremelFuge is a centrifuge rotor for use with a rotary tool such as the popular "Dremel". As an Open-Source Hardware, DIYbio-inspired design it is intended to enable and inspire scientists world-wide.

At a rotary speed of 33,000rpm (the top speed for a standard Dremel 300), Dremelfuge can deliver up to 52,000g/rcf (1g = the force of Earth's gravity) on a sample in a standard 1.5ml microcentrifuge tube, measured halfway down the tube. This far exceeds the speeds typically used in lab protocols.

Dremelfuge can be used to collect bacteria, proteins, DNA or anything else suspended in a sample. Dremelfuge can be used to extract plasmids from cultures, to purify and cleanse DNA after enzymatic reactions, to remove precipitated impurities or for any other task calling for a powerful centrifuge.

It requires only the 5mm cutting tool holder that comes with the Dremel 300.

For safety reasons, Dremelfuge is sold as an ornament or curio; although demonstrated to be effective and reliable for routine lab tasks, use of Dremelfuge for any task other than as a decorative item is performed entirely at the risk of the buyer. It is suggested that all appropriate safety precautions be taken in such cases, including but not limited to eye protection.
