I have taken the liberty to whip up a quick "Wheel Generator" in OpenSCAD... Probably doesn't rival something that Andrew Plumb would put out ;) but it should get the job done...<div><br></div><div>It's set for higher precision circles, and lets you tune all the parameters you like to make a nice wheel...</div>
<div><br></div><div>Just download OpenSCAD from <a href="http://www.openscad.org/">http://www.openscad.org/</a> (scroll down to the releases page, I'm using the windows version just extracted the zip and ran from the folder).</div>
<div><br></div><div>then open up my script (attached) at the top there are several lines of parameters you can change about the wheel. When done tweaking, hit F5 to render it and see what it looks like... you can revise as much as you like and keep hitting F5 to re-render.</div>
<div><br></div><div>When done just send the scad file back to me and I can render it out to an STL and print from that.</div><div><br></div><div>Or if you wish you can hit F6 to render CGAL, then go to the design menu, and export as STL, and most people should be able to print from that, or cut it on a CNC I would imagine.</div>
<div><br></div><div>Let me know if you want me to print it. I believe I might have enough plastic on the UP (more coming Friday I believe) and I hope to have my reprap back in working order by tomorrow (and it has tons of plastic lol)</div>

<br>
I have attached a google sketch up of what I was hopping to have or<br>
similar. the wheel does not seem to be as round as i would like.<br>
<br>
the inner circle part is 5.5mm wide and 4mm high. The rest are just<br>
approximate 10 cm diameter wheel 1 cm thick (to put an elastic on it)<br>
Let me know what you think.<br>
<br>
I don;t really thin 10 cm will be too big. I think the motors are<br>
powerful enough.<br>
