description: """
DremelFuge is a printable rotor for centrifuging standard microcentrifuge
tubes and miniprep columns. Compared to the cost of a new centrifuge
(priced by a fellow Thingiversian at $500 minimum on Froogle), a Dremelfuge
is incredibly cheap. It can be used for DIYbio ( diybio.org ) or for some
culinary uses. It requires industry standard 1.5ml/2ml
Eppendorf/Microcentrifuge tubes.
* Used with a drill at 3000 RPM, the Dremelfuge will deliver over 400g,
enough to comfortably spin down Miniprep samples (proven personally).
It will likely achieve acceptable results at lower speeds, too.
* Used at 10krpm, on a Rotary tool for instance, a Dremelfuge should
deliver over 4400g, more than enough to spin down bacterial cells.
* At 16krpm, Dremelfuge matches commercial centrifuges.
* On a Dremel 300, a maximum speed of 33krpm equates to a force of over
50,000 times earth's gravity, which puts it into so-called
"Ultracentrifuge" territory. The latest version (as printed by Shapeways)
has successfully spun tubes at this speed.
To see some picures of Dremelfuge used to spin down cells, see here:

(Update: This video hit over 1900 views! Thanks Makezine/Bre!)
Dremelfuge is available for sale as a high-quality, robust print on
shapeways.com in two editions, each suited for up to six samples at a time:
* Dremelfuge Recessed Edition, to fit the cutting-tool-holder commonly
found with rotary tools (5mm diameter bore)
* Dremelfuge Chuck Edition, which can be quickly adapted for use in any
machine with a chuck grip.
Dremelfuge, as with any high-speed rotary tool, may cause personal harm or
damage to property or persons in case of failure, and no guarantee,
warranty, promise or suggestion of safety is made or offered by Cathal
Garvey with regard to DremelFuge.
Please let me know if Dremelfuge is of use to you! Please upload pictures
of any printed Dremelfuges in the wild! :)
