1598_PART.jpgThanks for taking the time to reply...I have attached the part drawing to my message if that will help. Yes, there is a STL file as we have the step file for the model provided by our customer. As for modeling I prefer to use Inventor but I do not have that downloaded on my personal computer. I recently downloaded Cura for my 3D printing, but I am open to trying new programs since I have only been tinkering with this for about a week or so. Let me know what you think and if I am in over my head lol
