Idk if I ever told this story, but my current 3d printer (Prusa MINI+), I got used on eBay to replace my old Ender 3, which I gave to a friend.
The Mini, for those not in the know, is a cantilevered printer. This means the X axis - a horizontal beam - rides up and down on a single tower, connected at the right edge. This makes it cheaper and simpler, at the cost of some rigidity. It's not a great design for shipping.
The guy told me he was going to research how to ship the printer without disassembling it. If you order the printer new from Prusa, they take the vertical tower down and lay it flat. This requires some assembly work, but vastly reduces the odds of something breaking in shipping. I told the guy to just do it that way - I have a lot of experience working with printers, it'll be fine.
He didn't listen, and put it in a box with expanding foam bags to support the structure during shipping, insisting it would be fine.
Guess what showed up broken.
He refunded the shipping costs and I was able to reprint the broken parts, but still.
