I was in too much of a hurry to use my first one, so it was just named “Glowforge” and I felt kind of guilty when I’d see all the clever names other people had given theirs.
Then it died, so while I was waiting for its replacement I made up for my initial shortcoming by giving the second one TWO names: “Ignatius Ordgar” (sharp fire).
Alas, Ignatius lived a very short life, and was replaced by #3, which was named “Charm” (because it was the third time, and I hoped the last!). My optimism was unfounded, however, as Charm also had to return to the mothership.
By then I’d become a bit jaded about the whole “cool name” thing, since it felt like an exercise in wasted effort, so #4 was just named “Four.” (There is a book I enjoyed with a character named Four, so that helped to justify my laziness.) So far, Four has been steadfast (as was his namesake), so I’m looking forward to a long and happy life with him.
I’m all out of names, so I don’t really have any suggestions. But I really like your jars!
