Came across this in my browsing.  This might fix up the STL export problem we have been seeing.

so Nate, did this work?

It worked, but i don't use it much.  There was something about it that I was afraid it would mess up the entire part.  I've just been repairing my stuff by hand now. 

ok! yeah NetFab i think i use>?

coool~

yeah i like netfabb, then it's just fixing the STL file and not modifying an entire sketchup file.
