Very Customizable Fidget Spinner
type of weights: 5/16″, 3/8″, 1/2″ nut, M8, M10, M12 nut, 608 bearing, 5/16″, 3/8″, 1/2″, 5/8″ loose ball bearing, US penny, nickel, dime or quarter, M4 square nut
number of rays
number of weights per ray
edge roundness (radius)
tapering of rays
Added “minimal” ray style that just consists of the weight frame. If using an extended ray with one weight per ray, a thin bar will connect the weight to the center.
added M4 square nuts as suggested by nattrassj12
added the option to use 5/16″ (8mm) loose ball bearings
added the option for horizontal glue grooves for center 608 bearing and ray weights
added the option to use loose ball bearings: 3/8″, 1/2″, and 5/8″ (tested with 1/2″ and 5/8″); for a heavy, long spinning spinner. Thanks to stolli666 for the suggestion.
added option to taper rays or not; without tapering, the ray will be more rectangular and less triangular
added M10 and M12 nut sizes
fixed low resolution bug
added 3/8″ and 1/2″ nut choices for weights
nuts will protrude but didn’t want to require supports or have an asymmetrical frame
added the ability to extend the ray length when using only 1 weight per ray
added coins to type type of weights: 4 quarters, 5 dimes, 3 nickels or 4 pennies. But I prefer nuts or bearings for weights.
A 4 ray, 1 weight per ray, 5/16″ nut, 2.5mm radius version is very compact (easy one-handed spin) and fun! Give it a try.
Customizer might time out but the Create Thing button still works
I like using vise grips to install hardware
Cheap 5/16″ hex nuts from Amazon
if a nut is loose in a PLA frame, dip nut in frame into hot water to shrink frame around nut
