<p>Create chaotic movements by moving your finger a few centimetres back and forwards.</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>LulzBot</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>TAZ 5</p></div><strong>Rafts:</strong></p> <p>Yes</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.31mm</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div></p> <p><strong>Notes:</strong></p> <p>Higher layer height reduces the amount of knock that happens between layers, which is important for tall structures and a stupid GCode generator.</p> <h3> Instructions</h3> <p>Place the thing that looks a bit like a stethoscope end on top of the ring with the weight at the end (no glue necessary), then move the other ring around on a flat surface with your finger.</p> <p>I was watching someone playing with one of my spinning tops, and they couldn't get the hang of twisting the top to make it go -- all they did was move their finger back and forwards. I created this spinning toy to see if I could make something interesting out of such a movement.</p> <p>I've discovered a couple of things by a bit of playing round with the printed model:</p> <ul> <li>The pivot that attaches the smaller pendulum could be a bit wider. With a careless use of the spinner it tends to come free too easily. </li> </ul> <ul> <li><p>The place for your finger is a tad too small. A couple more mm of radius on that should fix the problem. These changes are implemented in the v2 model.</p> <h3>Version 4</h3> </li> </ul> </p></p></p> Category: Mechanical Toys
