tinkerCentrifuge MK1, DIY tabletop centrifuge for eppendorf tubes

thingiverse

We have a mixer for our laboratory (http://tinkerheart.eu/tinkervortex-mk1/) – now lets make a separator, or, to be more precise: a centrifuge, which will let us separate fluids of different densities, or separate solids from liquids. Quite neat. As with my other projects I’ve tried to keep the cost low while still getting decent performance from my machines – the tinkerCentrifuge sports a 3800 rpm motor and can spin up to 8 or 24 tubes at a time, depending on which rotor you use. A few words about safety: This machine has exposed moving parts and can be dangerous to use, especially if not constructed properly. It is not a toy, not for kids and if you build one I recommend that you use it behind a protective shield (such as a laboratory acrylic shield). Always protect your eyes (and other people’s eyes). While I can’t promise anything regarding strength and durability of the centrifuge rotor or other parts as those things depend on many factors, the 8-tube centrifuge rotor is more rugged than the 24-tube centrifuge rotor… and I suspect that 8-tubes is more than enough for most laboratories. The 24-tube rotor is mostly included since I am considering making a more robust version of it, and I might as well let you people get a chance at doing so too.

Threaded parts should be printed at a layer height of 0.2mm or less. 3 perimenters and 10% or more infill works well for me for most parts, but I print my centrifuge rotors with 50% infill.
