LOL yeah, not sure what else to call these, its a tube and its for a vacuum.
Comment on Partner broke the vacuum tube, so designed and printed replacements.

Man, I’m old. I was wondering how in the heck you 3D printed a glass and metal vacuum tube.

Sintered glass and using solder like filament!
(Okay that might be too ugly, even by my standards….)

No current hobbyist sintered glass printer can make a vacuum vessel that can withstand the needed negative pressure unless you make the walls prohibitively thick and even then probably not.

That’s funny. FYI… I’m not the one who downvoted you.
Second fyi… you can post process. For sintered glass, you can print the part and then fire it either in a kiln, a furnace or an a torch.
Finally, you speak with such authority on what mere hobbyists can do. I wouldn’t put any wagers on that.
