Hand crank centrifuge

One of my very first prints, post-processing may be required for shaft parts to fit (light sanding). I updated the files so that sanding won't be necessary.

This hand cranked centrifuge takes 5 mL tubes and can spin liquid down to avoid wasting precious sample.
The rotor is separate from gear #3, and the rotor holder, so that different rotors can be designed when needed.

Gears are not mine, I used the models from: https://www.thingiverse.com/thing:1946982
