Comically Large Ball Bearing-3D Printing and More!

I made a comically large ball bearing into a comically large fidget spinner. And now you can aswell

Step 1: CAD

Start by designing the ball bearing in Fusion 360. Create a square 6 inches away from the center point. Within the square, make a circle with a half-inch diameter. Use the revolve tool to make the rectangle go around the center point to make a full circle. Ensure the circle in the square is cut when it becomes a body so the balls can flow through. Once the circle is extruded, split it into four to make 3D printing easy. 3D print the pieces.

Step 2: Supports

You will then measure the inside parts of the 3D-printed pieces. They should measure about 11 inches. Using a CNC machine, cut a perfect circle to support the inside pieces of the ball bearing. Finally, you now want to cut a ring that is about 1.5 inches bigger than the inside support (measure everything yourself to be sure)to support the outside pieces. Glue the 3D pieces onto the wood supports.

Step 3: Put It All Together

Put it all together now. You might want to melt a small hole into the 3D-printed inside to insert the balls. The End.
