Slic3r error only on galaxy S3 cases?

I have gotten that error before on my own designs.  A simple test is up the scale by 5 or 10 percent and see if it slices that way.  If it does then the problem is dimensional in nature and you can cheat your way around it by changing your nozzle diameter settings.  Of course this can open a whole other can of worms.  Basically Slic3r is coming across some dimension in the design that it just can't figure out how to make it work out as multiples of your nozzle diameter.  Usually small detail stuff causes the problem.  If it is a design of my own it is easy enough to use dimensions that at a multiple of the nozzle diameter when working in the finer detail parts of the design.  The other thing that can cause this is if you have perimeters set to high and the design doesn't have enough room for all the perimeters.  For example an area of the print needs to be 3mm across and you have 4 perimeters set in the profile.  That would be 1.92 mm's for each side for a total of 3.84 mm's. so the perimeters would have to collide and Slic3r can't deal with that so you'll get that error.

Those are the two situations that have caused that for me.  I would start at the number of perimeters set first.  Something like a phone case should be printed solid any way so you only need a couple of perimeters.

Are you sure you changed to that profile after you made and saved the changes.  What file link is it I'll try and slice it and see what I come up with.  Sometimes the file is just bad and not printable.

Sure give me a few minutes.

I'm not sure what I'm looking for in your picture but my settings are all pretty standard for 0.3mm layers.  I can slice literally anything else, including objects with thin edges so I'm still pretty lost here.

Also,I did run it through nettfab I can send you that file if you want to try it.
