All parametric bevel gear generator in OpenSCAD. 

Attention: Only 45 degrees twins gears will math. 

You can try to correct they manually. 

The program use the internal and external diameter of the gears to create the teeth. 

Different number of teeth, different height or different degrees will create gears with different teeth. 

I am working on it... ;-)

The Pinshape site do not accept .scad files.

The OpenSCAD file is inside the file: "Gear_Bevel.zip.stl" .

It is a .ZIP file not a .STL file, just rename it and extract the OpenSCAD file. 

Thanks.
