This is a Portal Weighted Companion cube turned Fidget Spinner. All 6 sides hold a 608 bearing. The STL files give you the main body and the heart buttons. You will need to print 6 of the buttons (obviously). The pictured spinner was printed in PLA @ 0.2mm layer height. You will need to print with supports for both the spinner body and the buttons.
