Also I see we finally got enough lists in before the deadline to knock off any single-voter-number-one entries from squeaking into the top 50, so I guess I can spoil mine, which I was pretty dang sure nobody else would vote for (except apparently Mogri's brother who isn't voting) - the Desktop Milling Machine. Think of it as the opposite of a 3D printer, just much louder and can make things out of like metal and wood and such. Some might argue it's more of a machine shop supply, but it's on my office desk, so there. It's also the ultimate meta-supply. Missing some other supply? Make it yourself! I bet I could make a passable paperclip on this thing... or a box, for that matter.
