Trouble Getting a Sketchup File to Print

Hey guys/gals,

Hope this is the correct place to post about this.

My girlfriend is making a few things for me in Sketchup and I cant figure out how to get them to print. Been using Guitar-List to convert her files to STL format, but I'm getting Manifold errors. Went back and edited the file as best I could using the wiki as a guide, but still getting manifold errors and such.

This is just a simple Ying-Yang symbol, so I was hoping someone could open it up and give us a better idea of what we are doing wrong.

The project she's working on now is a shot-glass chess set. It'll benefit everyone if we can get the files to Slice correctly.

OH! Using Sketchup 8 and Slicer 0.8.4

I should have looked harder... There was an internal face that was keeping the whole thing from working. My bad.

Chess set will be posted when it's done, so check back on my Thingiverse page for a copy!

Thanks for looking everyone!

Good deal!

How did you hunt down the extra face?
I have been using sketchup as i got a 3D printer to make prototype electronics housing boxes. I am assembling the models by extruding floors, walls, and lid parts then cutting and pasting together like lego parts. I cant get a good manifold with Sketchup even if I just extrude a big cube. I am sure it is just some setting I dont know about.
I am using Sketchup at the sub mm zoom so I can get an accurate sizing for my models as they have to snap together, I cant find anywhere that I can enter a number to get exact size and scale.

If it helps the file with holes is here, It is the box and lid for a USB charge controller board for 3.7v mobile phone batteries.
Maybe there is a plugin or something to unify the faces, maybe if sticking walls together like I did it is possible to disable intersection?
My file is free to use by anyone for any reason no rights reserved, steal this box!

@biketool: This type of object is done easier and quicker using OpenSCAD. See hundreds of box/chasis examples on Thingiverse (e.g. the Throated Box (Parametric)), the majority are parametric where you simply specify your dimensions and magically you have an STL file that you can slice and print.

I made the move to openSCAD today and can't belive the time I wasted with GUI editors. I am sure there will be a place for Blender or Sketchup for some projects like when I need text but I sat down with some graph paper and a calculator; I had a working printed model with all of the holes for the USB port, LEDs, and rubber cable flex thingie for an outdoor circuit box in a few hours with the help of a few tutorials and printing out a list of commands.
I would still like a GUI editor front end to speed things up that would output openSCAD code but I seem to be doing fine hand writing the code.

Most of my technical comments should be correct, but is THIS one ?
Anyway, as a rule of thumb, always double check what people write.
