Yet another version of the fidget spinner.

All my friends want one and I was running out of 608 bearings. So I decided to create my own version that uses heavy zinc-plated 1/2"-13 nuts for the counter weights.

There are 3 versions with 3x, 4x, and 5x nuts. Each spinner uses a standard 608 skate bearing.

Print the following:

• 1x spinner body (3x, 4x, or 5x)
• 2x grips
• 1x assembly jig

The 1/2" nuts I used are 11.2mm tall. The spinner body is 7mm high (to match the height of the 608 bearing) which leaves 4.2mm difference. The assembly jig is used to center the nut in the spinner body.

The tolerance for the nut inserts is very tight. You will need to use a rubber mallet.

1. With the spinner on a flat surface, use the rubber mallet to push the bearing into place.

2. Now put a 1/2" nut in place, on top of an insert. Carefully pound the nut until it meets the flat surface.

3. Repeat this for each nut. At this point, all nuts are all overhanging on the hammered side.

4. Place the assembly jig on the flat surface while aligning each of the nuts so that the nut can drop through the jig and hit the flat surface when hit with the rubber mallet. (see photo)

5. Push the bearing grips into the bearing.

Note: The grips have extra spacing on them so they clear the nuts on each side to allow for spinning on a flat surface.
