does this fidget needs bbs as bearings?

No bearings needed. The printed gears rotates on a cylinder like a bushing.

The screenshot of the Cura slicing software shows everything needed to make one.

You may need to rub with sand paper or carefully scrape with a knife to get things to rotate smoothly.

Great work, but i have a problem: When i slice the Housing_2, the sistem recognise the empty space as a full space or something like that, and it fills it, with infill and with top/bottom. Help.

Nice design! I printed the more "advanced" one and it works great!

I've made a few. Some of the gears drop right on to the cylinder, and some of them do not. I had to sand paper or scrape to make it fit nice. I also had to scrape out all of the little hitchhikers in the gear teeth.

You should post a mirrored model of the gear for non-90˚ intersection. At the moment, it is only possible to make 90˚ intersections.

In the extras.zip, There are extra parts, including both LH and RH gears. There is also just a cylinder, if you want a different colour on the inside.

On my other Helical Gear Fidget Toy that I made, there were some comments about having too many files/options. So I trimmed this one.

Otherwise, most slicing software will let you mirror, effectively producing the opposite hand gear.
