Machining a Fidget Spinner

Machining a Fidget Spinner

Determined after my previous attempt to make a fidget spinner, I tried once again.

Learn about how I ruined a $55 end mill, embraced failure, and hopefully never repeat my mistake yourself.

This attempt was a significant improvement, as reflected in the below show reel.

The design of the fidget spinner is very similar to the first attempt with a spinner body, a bearing, and two finger contacts. Different from the previous attempt, the finger contact now includes a star-like geometry to aid with grasping.

Machining the Spinner Body

The main body of the fidget spinner is machined from a large block of aluminum. This might seem wasteful except the block came from the remnant of a larger machine shop; it was already destined for recycling. I did recycle the chips.
