I'm printing the first prototype right now. I'll see how it goes, and if the problems you predict arise. It's a cupholder from thingiverse that I've modified slightly for the application. My starting assumption is that, in its original form, it was working and strong enough for its designer. We'll see if my assumption was warranted. I added the part that goes under the cup/can, and changed the mounting bracket. The original was made to hang onto an existing cupholder. My mounting method should be stronger than the original, but I can beef it up if I need to.
I happy to have any advice from a more experienced 3D printer!
