Not a valid STL file


I wanted to print a small cilinder today but i couldn’t because the stl file appears to be invalid.

I am using a student version of solidworks and never had this problem in the past. Since i used the newest version released in 2017 (starting this schoolyear sept 2017) i did not try to print any object until this one.

Is there something i can do to make my object a valid stl? It’s just a simple D=12mm d=6,5mm H=20mm tube.

Kind regards,

You can try two online services that validate .stl files and make corrections if they’re simple enough:

They both require signing in, but are free. I hope this helps.
