A 3D printed accessory to turn your Dremel into a centrifuge. Shown here spinning up to about 17000 g's. Sufficient for many scientific applications. Based on http://www.thingiverse.com/thing:1483 but with a swing bucket to ensure samples are returned to an upright position after spinning.
THIS IS EXTREMELY DANGEROUS. If you use the swing bucket Dremel centrifuge as shown above you should expect that it may cause serious harm to you or any nearby objects.
I initially used some small nuts and bots but then the notion of those things flying off at 100mph sort of terrified me. I ended up using some thick wire.
