This is a fidget spinner that you attach to some kind of base with a single screw. It consists of several 3D printed pieces, modified ball bearing and possibly several washers for M5 bolts.
The modified ball bearing in question is the 608 ball bearing. What you need to do in order for it to have smooth operation is to remove the guards, soak it in acetone or IPA and remove the grease with a toothbrush for example. Finally spray it with some low viscosity oil like silicon oil.
Printing:
This is quite easy print, but you need to have good bed adhesion. In order for the spinner to spin much longer it is necessary to weigh down its arms. I used 4 washers for M5 bolts into each arms cavity. Just pause the print at 7,5 mm height and insert it.
Print it with 4 walls, 15% adaptive cubic infill and no supports. I use 0,3 mm layer height but you can go lower.
Assembly:
Just put everything on the screw (screw goes from top) according to the photo and screw it to the base. The FS-04 should snap in place but if it does not, just drop a little bit of super glue to the side.
