Mini DH Geared Fidget Spinner

thingiverse

This is a double helical geared fidget spinner. It relies on friction fit between bearings, no additional hardware required. The center bearing is held in place by surrounding gears. You'll need to print: 4 x DoubleHelixGear 2 x Spinner 2 x Bearing Button Four 22mm bearings (608Z) are used. Print the gears, spinners, and buttons. Push the bearings into the gears; pliers may be needed but handle with care to avoid breaking the gears. Insert the bearing buttons into each side of one of the bearings. Next, push one of the bearings onto the spinner piece, possibly requiring pliers. Line up the bearing with the buttons in the middle of the spinner piece, ensuring that the gears fit interlocking with those on the bearing attached to the spinner. Then push the other two bearings onto the spinner piece, making sure the gears align with the middle bearing's gears. Finally, insert the other spinner piece into the bearings to complete assembly. Let me know if any improvements can be made!
