This is a fun, custom fidget spinner that requires no supports, if you want you can put 3 8mm ball bearings into it to make it spin longer. the bearings pressure fit into the spinner, so there is no glue required. If the balls in the 3D printed bearing are stuck, I recommend using the Creality pliers to break them free.
The spinner with external grips allows you to have better thumb grips to hold the spinner on both sides- Note: there is some assembly required with this fidget spinner.
