It has held up fine! Super sturdy and not a single doubt in my mind that it will last as long or longer as the original. I can put real heavy loads on it without any issues. I don’t think the layers are a problem in this application.
Printed the same as you, a standing tube. I used PETG for the best layer adhesion. The walls are 3 mm thick solid. It has held up fine so far, but i haven’t had the opportunity to put heavy use on it yet.
I actually thought about it before printing it and my backup plan is to print it at 45 degrees angle with more supports if it doesn’t hold up.
