  <title>Whole object is non-manifold, 20.3MB stl file</title>

  <description><![CDATA[It would appear that my model is suffering from multiple problems.  I am proficient in Illustrator and Sketchup, but Blender is a bit overwhelming my first time in.<br />
<br />
First, the main logo consists of just under 300K vertices, most of which are completely pointless.  Is there some tool I can use which will automatically eliminate vectors which do not create an angled face?<br />
<br />
Second, I followed the tutorial to resolve the non-manifold error, but my entire model (all 300,312 edges) are selected.  Perhaps there is a tiny hole somewhere in my shape, but I can't find it.  Is there a script or easy means to locate that?<br />
<br />
Thanks!]]></description>

  <description><![CDATA[Okay, despite being pretty sure I'd removed duplicates once before, did it again and reduced the model down from 300K edges to 19.5K edges.  A significant improvement, to be sure.  I suppose now it is not as essential to reduce the number of worthless polys in the main logo, but it would be nice.<br />
<br />
The non-manifold bits left over are a gnarly bit of nearly hidden shapes that I could just as easily do without.]]></description>

  <description><![CDATA[Here's your main problem. Red indicates flipped normals.<br />

<br />
I've attatched the fixed file for you, but I still think it'll need some work. A lot of your conversion artifacts are quite small and will probably flag the shapeways systems for minimum feature size.<br />
<br />
I recommend exploding your model into shells, deleting all the unnecessary junk, and then boolean everything back together.<br />
<br />
Also, converted your model to mm. <br />
