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.
Will do! Planning to put some OSB boards up this weekend. Should be a fair test by going through a stack of ten boards.
