@twitter #fidgetspinner 2, 3, or 4 birds weight choices: 5/16", 3/8", 1/2" M8, M10, or M12 hex nuts, 3/8", 1/2", or 5/8" loose ball bearings Notes you might want to click on Thing Files to just download the files you want, because "Download All Files" will download all options (28 MB) I like using vise grips to install hardware if a nut is loose in a PLA frame, dip nut in frame into hot water to shrink frame around nut See my collection of all of my fidget spinner designs.
