The new fidget spinner! I have tons of bearings left over from when they were popular. I was designing a hinge for a desk light when I had a two rigid pendulums with bearings in them. I stuck them in wood dowels laying around when coming up with a hinge mechanism. After playing with them around for a while, I tried spinning them in opposite directions and came up with this fidget toy. This is what I came up with after refining the design.

Step 1: Parts

Bearings x4
5/16" Wood Dowel 20 cm
3D printed parts
- bar x2
- dowel cap x2
- end cap x2
- spacer x1

Step 2: Assembly

Use a mallet to get the bearings into the bars.
Slot 3D printed pieces and bearings into the wood dowel in the order end cap - bearing - spacer - bearing - end cap. Super glue or hot glue the end cap to keep in place.
Glue on the dowel caps to hide the splintered dowel.
Spin and have fun!

Step 3: Conclusion

I'd like this to catch on as much as fidget spinners did. We'll see what happens. It took me no time at all to make and it came as a result of me playing with things I had laying around. Hopefully I'll have my desk light done soon. Maybe I'll advertise it as "The light that inspired the fidget bar!".
