No special settings needed. I used 10% grid infill for the body and 20% for the other parts.
Print the handle you prefer and all other parts from the Shared parts folder
Print all parts from the Patterned folder
I have included two versions of the beads, one larger and one flat. The larger one increases the air resistance which reduces the spinning time a bit (not much but noticeable).
Print the body and your preference of beads from the Beaded folder
To increase performance and lifetime you should lubricate the threads of the screw and driver parts with silicone spray or other suitable (non greasy) lubricant
Glue the beads/pattern parts to the specified places on the body and let the glue dry before continuing.
