#3D-printing #mechanical worm gears (though for some reason single-throated) and running them with no load and with or without grease. They melt at 8000 rpm when run without grease, but survive at least ten minutes at 12000 rpm with an unspecified grease. Printing the worms on a 45° angle with some support material works better than horizontal or vertical. #video
