HELP! Looking for someone to change the bore size of a gear!
Hello all, I'm looking for someone who can change the bore size of a gear I have drawn up. I no longer have a 3D program to open up the files so I can only get them from friends computers. I have an .igs and .stl file of the drawing that I can send to anyone that can help. The .stl file has been fine to open for a few weeks but all of a sudden it is saying "certificate trust list" and won't allow anyone to open it. If anyone also has incite on how to fix that I would love to hear it. Ideally, I would like the bore size changed from its 5.39mm to 3.00mm. Thank you!
