##Ball chain gear samples for 3.2 mm, 4.0 mm and 4.5 mm beads

I needed some ball chain gears as experiment for a thing ( https://www.thingiverse.com/make:929621 ) so I wrote a script that generated the essential part (correctly sized teeth) of the ball chain gear.

I generated more, maybe one will be useful for others ...

The stl filenames indicate the gear and ball size.

**BeadChainGear_x.y_aaa__bb.stl**
**• x.y - the bead diameter in mm**
**• aaa - the number of beads in a meter (pitch of the chain)**
**• bb - the number of teeth (hulls) on the gear.**

The center hole diameter is 2 mm and the thickness of the gears are 6 mm.
Each hull is a half sphere, and they are oversized with 10%.

Download the one that best suits your needs, modify it if necessary (bigger center hole, adding hub or sideplate, etc) to fit your thing. You can reduce or enlarge a few percent if necessary t
