I have the free Sketcup 8 version. I am trying to download the STL plugin. There are two downloads, one for Sketchup 6,7,8, and the second for Sketchup 8 maintenance release 2 and later. Anyway, I could not download neither one. I get a message says > Windows cant open this file, need to know witch program ...etc.
I want to buy a 3D priter which says it works on STL. anyone to help? thanks
