Laboratory centrifuge attachment for your Dremel tool

Just spotted this nifty concept by Thingiverse user cathalgarvey. He calls it a “DremelFuge.” It’s a centrifuge attachment for your drill or motor-tool that holds six Eppendorf tubes. Dunno how well it would actually work, as it looks heavy to mount in a Dremel tool, and most drills don’t spin nearly that fast. Still, clever thinking.
