I didn't use the original design because I wanted a standoff distance from the 608 bearing for the spinner. I used the Thingverse files from https://www.thingiverse.com/thing:3009552.
The central part worked fine but the hole for the bearing had too much clearance for my taste. If I were to print it again I'd change the hole size so that it was a light press fit for the bearing. If you prefer to use glue to mount the bearing you could leave the hole as is or still shrink it slightly. The Multi-Material 2S is used to go from gray to black and back to gray but you could change filament manually if you can only print one color.
