Problem is going to be layer adhesion. No matter if I orient it horizontally, or vertically. If injection molding can't stand up to the pressures I'm using, I doubt additive manufacturing will.
Not trying to sound combative btw! I appreciate all input and challenges to my thinking.
If your really want to go for it, you can order metal 3D prints from jlcpcb. They might require some post processing/polishing for this particular use.
You mentioned in another comment that you ordered some replacements from AliExpress. Those might last even less than the original ones. I would recommend take a look at GuliKit for good quality replacements.
I'm talking about the whole stick, which most likely extends into the device. Not just the broken-off piece of the stick.
If you're determined to avoid opening the enclosure to do the replacement, you might consider drilling a post hole into the remaining piece of the broken stick, and printing a replacement piece with a matching post, but I think you would get better results replacing the entire part.
Edit: Regardless of what new stick you choose, it might be worthwhile to reinforce it by drilling a hole in the center of its post and inserting a metal rod.
I don't know the particulars of these devices, though. It's possible that the stem part of the stick might be too short to easily work with, or the potentiometer assembly might be resist disassembly. Good luck!
