  <title>Mob-Tor (Moebius Torus)</title>

  <description><![CDATA[Hi all,<br />
<br />
I wanted to redo pendants based on marbles such as the <a href="http&#58;&#47;&#47;www.shapeways.com/model/26334/" target="_blank">double-marble pendant</a> for instance: I like the idea of mixing common existing objects with 3D printed models.<br />
<br />
I came up with the Moebius Torus, that I caled Mob-Tor to have something shorter.<br />
The idea is to put a number of marbles (for instance 3) into a torus, so that they can revolve inside it. To do that you have to cut this torus into two and keep only one half. I cut it a &quot;twisted&quot; way, like in a Moebius ring.<br />
Here is a rendering of the <a href="http&#58;&#47;&#47;www.shapeways.com/model/880498/" target="_blank">half Mob-Tor</a> to understand better:<br />
<a href="http&#58;&#47;&#47;www.shapeways.com/model/880498/" target="_blank"><img src="http://images1.sw-cdn.net/model/picture/674x501_880498_767947_1358796517.jpg" border=0 alt="http://images1.sw-cdn.net/model/picture/674x501_880498_767947_1358796517.jpg"></a><br />
The result is similar to the <a href="http&#58;&#47;&#47;www.shapeways.com/model/162900/" target="_blank">Twin Rail Mobius Pendant</a> of Stop4Stuff or the <a href="http&#58;&#47;&#47;www.shapeways.com/model/145172/" target="_blank">One ring to pwn the ball</a> of TerraCotta. These models are quite famous so I guess they have inspired me. The marbles are forced to move into &quot;tunnels&quot; like the first one (at least partially) and move along a simple circle like the second (see the <a href="https&#58;&#47;&#47;www.youtube.com/watch?v=1X0q6Gy-C8Q" target="_blank">video</a>).<br />
This is still a prototype, I don't even know if the marbles will stay inside the model without falling (or if at the contrary they could not be inserted). So perhaps some adjustements are needed.<br />
<br />
I also plan to have the two halves printed along with 3 marbles to get the <a href="http&#58;&#47;&#47;www.shapeways.com/model/882280/" target="_blank">Mob-Tor with marbles</a>:<br />
<a href="http&#58;&#47;&#47;www.shapeways.com/model/882280/" target="_blank"><img src="http://images1.sw-cdn.net/model/picture/674x501_882280_767933_1358796160.jpg" border=0 alt="http://images1.sw-cdn.net/model/picture/674x501_882280_767933_1358796160.jpg"></a><br />
Here it is easier to see the original torus. Once again, I have to test if this model is really stable or if the marbles will be easy to move.<br />
<br />
Any comment is welcomed.<br />
Thanks!<br />
<br />

  <description><![CDATA[Very cleaver design!  I see how you've removed the unnecessary parts of the torus while still leaving enough to capture the spheres.  Maybe you'll have the next big captured spheres design!  As a suggestion, I'd find out what the common sizes are for undrilled spherical beads and then make a corresponding Mob-Tor for each common size. ]]></description>

  <description><![CDATA[Thank you!<br />
I kept a contact of 60° on each side of the marble, with a clearance of 0.5mm. I hope this will be enough. For the half Mob-Tor, I could make those angles larger (say, until 90°) or reduce the clearance since the marbles will not be printed.<br />
Currently the pendant is planned for 5/8&quot; marbles (16mm) which should be quite standard for glass marbles (at least, this is the size of those I got from when I was a kid <img src="http://www.shapeways.com/forum/images/smiley_icons/icon_biggrin.gif" border=0 alt="Very Happy"> ).<br />
