Here's the effort.  Interestingly enough netfabb increased the triangles and size of the file.  I'll print it this weekend and let you know how it goes. 

Is this different enough where I would need to list it as a derivative at thingiverse or since I started from a blank page do I just call it my own?

It's solid so I could print it without infill and modify gcode to remove the top layers.  That worked out really nice since you can tell your slicer to have 2 perimeters and not have to try to get the shell thickness right and hope the slicer does the fill the way you wanted.  Just wish there was a way in skeinforge to tell it to do a base but no top.
