Working with 3D printing replacement early A-body parts

I have made quite a few parts in the last few years for my cars. As far as them not lasting I probably agree if you are using them on a car you use daily but for many of us our cars are treated better than some of our family members and only see any real environment less than 20 hours a year. Plus if you have a choice of a 3D printed part or nothing buy 2 or 3 of them and just change them out when they fail.
