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.
