stl files are linked in a zip at the bottom. I've never touched a 3D printer before so I don't know what you do with them, the online 2d printers I see want me

  STL files are the 3D models that you put into your slicer of choice (which converts the project into the thin layers that the printer will gradually put down). There's a dozen things to print in the zip. I sliced 3-4 of them, and none seemed particularly heavy. Something like $0.50 of filament each for what I pay for PLA, which would put the whole thing at ~$6 of material. Perhaps the cost is being driven by some sort of print-on-demand costs? FWIW, you could also buy an Ender 3 for ~$200, and $140 buys a lot of filament, so you could get into the 3D printing hobby for less than the quoted cost.
