Alright, I download the file again: Stereolithography (.stl)657 MB, When I unzip there's a error message: "The file has a unknow format or is damaged", I don not say is the file, maybe is my PC. Or maybe can be the size of the file is to big and some file inside is missing when I download.
Yes, I always open the file once is downloaded just to make sure it's the file I download. Right, I going to try to download again. I will report if there's problem for open.
the file is not damaged, have you unzipped it?
Seems the STL.rar archive is damaged.
