HandFuge - Hand-powered centrifuge

prusaprinters

<p>A 3D-printed version of the Paperfuge, based on ideas presented the following paper:</p> <p><a href="http://www.nature.com/articles/s41551-016-0009">http://www.nature.com/articles/s41551-016-0009</a></p> <p>The thin adapter pieces fit around a 1.7ml microfuge tube, which then sits in the grooves in the model. Make sure that the centrifuge is balanced (i.e. use 2, 3, 4, or 6 tubes at once, arranged symmetrically).</p> <p>Feed two pieces of &lt;3mm rope (e.g. old shoe laces) into the holes, twist the ropes together, then pull and let go to create a forward/reverse centrifuge action.</p> <p>For a single-direction hand-powered design, see <a href="https://www.thingiverse.com/thing:1807878">thing:1807878</a></p> <p>An audio analysis of my video suggests that this could be running at around 7,000 RPM (~100 samples per spin at 48kHz with four tubes).</p> <h3> Handfuge in Action</h3> Category: Biology
