Round toothed gears
by ketil, published
Stefano made a robotic gripper, and wrote some details on round toothed gears.
This is an openscad script that generates a round toothed gear with a round center hole, based on number of teeth and tooth diameter.
Punch in your details, change the hole shape as required, print and use.
The sample stl uploaded uses these values:
center_hole_diameter = 2;
The rest is autogenerated.
