Removed the outdated version of the .stl file and clarified the instructions for better understanding.

So the Readme change is good but we can't remove the STL's from that folder. The correct version should be uploaded in that folder so i'm making sure that's the case now and the ones in the main folder will be removed then since that folder is for ducts without probes. so if you take that our of the PR then i'll aprove it.

If you don't delete it, you will have redundant files, and the one that I deleted here is the old version.

By the way, it's always easier to maintain if all the .stl files (or any CAD files, etc.) are in the same folder and point from other pages into that directory. Otherwise, you will end up in such situations.
