Starmie fidget spinner using AMS and all PLA parts. The main star center cuts were originally cut for a 608 2RS bearing but I also included two bearing sized spacers in the design if you do not want to use the bearings. I found the bearings spin less freely than just the plastic spacers anyway. I numbered the order of assembly from back to front and the fitment is tight enough to use glueless, but I recommend to glue at least the star halves and the front and back pieces to the shaft and there may be some variance on your printer and settings. It is important the thicker of the two shaft spacers goes between the stars and that you do not put too much pressure against the stars if you are not using the bearings
