About this 3D model
Fish Fidget Spinner (customizable) Customize: type of weight: 608 bearing, or hex nuts: 5/16", 3/8", 1/2", M8, M10, M12 Edge roundness (radius) number of fish: 2 to 4 Update 2017-04-11 added the option to use loose ball bearings: 3/8", 1/2", and 5/8" (tested with 5/8"); for a heavy, long spinning spinner Notes: Download my favorite: three fish with 3/8" hex nuts with radius of 3mm. Customizer will time out when radius > 0, but the "Create thing" still works nuts larger than 5/16" or M8 will protrude but I didn't want to require supports or have an asymmetrical frame 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.
