To start, .01" is too small to be printed in stainless, or any material for that matter. Stainless requires 3mm (a little less than .12" I always use .12") and the smallest any material can do is 1mm (I use .04") Check out under the support tab, Materials, and it will give you all the restrictions for each material.
As far as your problem. When you uploaded did you select inches as your units? The dimensions I'm getting on your model match the units that Shapeways gave you.
Studying further, it appears your SolidWorks is set to mm, as 6.35 (the height I'm getting for your ring) If I take that as mm and convert to inches I get the .25" you stated.
Studying even further I see that you had that marked out on your model
. Just upload as mm and it'll upload as long as it doesn't catch that it is too thin to be printed.
