I created this planetary gear spinner in CAD and refined it in Bambu Studio.  This is a great spinning fidget with a cool gear design.  There are small pegs on 2 opposing sides of the spinner to help give a tactile feel when you hold it with your fingers if you want to spin the individual gears. It is PIP and there are no supports needed.  It takes an hour to print P1S & uses just over 18 G of filament so it is filament use friendly. It is SUPER SMOOTH!!

Enjoy the spinner!!
