Printable SpinBot - ArtBot

prusaprinters

<p>I went to Maker Faire Bay Area 2009 and saw these cool little robots that held pens and drew lots of spirograph style drawings as it spun around. Unfortunately, I got distracted by something and forgot to go back to it.</p> <p>I didn't get to go back to Maker Faire until just this last weekend. Fortunately, my daughter immediately caught sight of these robots and we built one together. It was a lot of fun to build with her and a lot of fun to watch in action.</p> <p>A Spinbot is basically a tripod that has pens in place of two legs and a little motor with a rubber nub as the third leg. Start up the motor and set it spinning and drawing. It's a simple device, but a lot of fun to watch.</p> <p>Here is Chris Myers' page on the Maker Faire website: <a href="http://makerfaire.com/pub/e/5241">http://makerfaire.com/pub/e/5241</a><br/> And, here's Chris Myers' website with a few other pictures: <a href="http://www.isopoddesign.com/6.html">http://www.isopoddesign.com/6.html</a></p> <p>Chris' design uses lasercut acrylic pieces (some of which have been heated and bent), zip ties, double sided tape, and rubber bands to hold the pieces together. The heat-bending of the acrylic is necessary to give the flat pieces acrylic the ability to form a tripod.</p> <p>After looking it over, I decided it could probably be made into a very printable form. This is my shot at it. Rather than creating a strict copy of Chris' work, I wanted to make a variation that would (a) be smaller (b) be printable in one piece and (c) enable to user to use fewer additional parts. One of the trade-offs is that I had to angle each of the legs at 45 degrees so I could avoid the use of support structures. The legs in Chris' designs appear to be at about a 30 degree angle.</p> <h3>Print instructions</h3><p>Unassociated tags: art bot, spin bot</p> <h3>Instructions</h3> <ol> <li>Print.</li> <li>The attached SCAD file is designed to allow you to use either the 4x AAAA batteries the original Spinbot uses or it has just enough room to hold a 9V battery.</li> <li>Add motor, switch, batteries, pens, and draw!</li> </ol>
