The printing process is not perfect. Though it may work perfectly in Sketchup a little bit of clearance is needed to compensate for the printing inaccuracies. This happens to be a common problem that is pertinent to all manufacturing methods, not just 3D printing, and most high end CAD software have commands for automatically checking the clearances of parts in attempts to avoid the problem of not seeing interferences.
You need to check the clearance between the two parts, where they slide against each other. The cutting blades should be zero clearance, but everything else should have a little clearance so that they can slide against each other without binding.
If you need help with adjusting the clearance you can add your model as an attachment and one of us will be happy to add some clearance for you. 
Let us 3D print the universe. Oh wait! Maybe we already have!

I am no longer in need of help on this project. Designer has submitted me a design.

All I did was change the texture format to .jpg, and it uploaded. I saw it with the correct texture and I ordered it. Yeah!
Now, all I gotta do is wait for the "thin walls" email. haha!
I don't know what that netfabb program is, but the model is sitting at the origin, transforms are frozen, and it is closed. I did not have to add extra quotes to the .x3d file.

I want someone to sign a coin I designed and printed, but one of the questions raised was, what kind of markers work on the material? I'd test it out, but I don't want to ruin the printed canvas meant for someone else. Any tips would be great.

Perfect! Got a new/old Paasche air eraser on ebay, $40, and a pound of baking soda from the kitchen, it worked great... parts are all clean now (finally).
No love on the small chain, Shapeways refuses to print the small size (wire < 0.6mm).

Welcome to grit blasting!! There are vids on you tube about this process. Interesting stuff.
I don't understand why Shapeways won't go smaller then .6mm. The radars I have have smaller that .6 for sure. Those are the ones's that
the air eraser can blow off the simulated radar array.
I wonder if they changed their file qc processes. I suspect that it could be the file format, .STL vs cad vs whatever. I do know that the IJN parts are done
in a stl file format as Shingo did a screen capture of one of his designs. And it said stl.
I believe the smallest nozzle size .3mm. Maybe the printer is different from your chain and my IJN stuff...
I just checked on one of my screwed up radars and it is definately smaller then .6mm
