Fidget Spinner

Fidget Spinners are easily mass producible and area fun toys to distribute to kids. With this tutorial you can design your own spinner that you can either keep for yourself of give to friends or family.

Step 1: Design the Base
Open Fusion 360 and create a new sketch on the top plane.
First make a 22 mm circle, then make another one around it at any size you want. This will be the starting base for your Fidget spinner. The bearing should be able to fit in this area snuggly.
After this, create your own design around the spinner. You should make this only on one side then do a circular pattern to keep all the weights balanced.
You can do this my either taking a design off the internet and using a fit point spline to copy it, or by making up something by youself
Remember, the more weight on the edges, the longer it will spin for
For better spinability, create three bearing holes around the central hole to increase the weight on the edges even more.
If you're unsure about a design, search for fidget spinner outlines online, import them as a canvas in Fusion 360, and trace them using the Fit Point Spline tool.
Once satisfied, Extrude (E) the base to 7mm thick.
Finally, add chamfers to the bearing locations and filet the edges so it is comfortable to spin.




Create a new component.
Start a new sketch on the top plane.
Draw a circle for the outer diameter of the cap.(can be 22mm up)
Draw a smaller 8mm circle in the center to fit inside the ball bearing.
Create a raised cylindrical peg:
extrude this circle circle centered on the 22mm cap.and extrude it 2 mm.
create another circle on top of the recently extruded circle with a diameter of 2-4mm.
If you want to make it spin a little better add small filleted slots on the edges of the center bearing
Extrude this to 1.5mm
Fillet (F) the edges for smoothness.
Step 2: Create the Female Cap
do the exact same thing for the second cap but this time when extruding the smallest circle, make it go downward
This means it should be the opposite of the male cap, making it so they should fit together perfectly.

Export the base, male cap, and female cap as STL files.
Use a 3D slicer (like Cura) and print with PLA or PETG.
Insert a 608 bearing into the fidget spinner base.
Snap the male and female caps together over the bearing.
Test the fit and enjoy spinning your custom-designed fidget spinner! 🚀
