Hypoid gear modelling - been done in OpenSCAD?

I would like to model a car differential gear set for a personal project.

This uses Hypoid gear drive – similar to this: https://www.thingiverse.com/thing:1888576

The Hypoid gear goes a bit beyond the usual spiral bevel gear libraries, as there’s an offset shaft as well as curved teeth…

I’ve found a few examples of people having done this in Blender, showing their working, and there are online calculators, so eventually I imagine I could recreate these – but would be brilliant if this already exists in OpenSCAD – anybody seen this please?

Cheers,

Alex Gibson

I tried to generate hypoid gears years ago, but my gear theory was bad at the
time. Maybe I should take another crack at it.

I could only encourage this :)

Some research aids!

This is a true hypoid already created as I mentioned already:
https://www.thingiverse.com/thing:1888576
This actually comes with a full tutorial for creating it in Blender - and
even better from the maker, an online calculator:
http://www.otvinta.com/hypoid.html

Here are a few already good OpenSCAD gear libraries, it would be great to
build on one of these to give any new function maximum reach - one that is
referenced by a lot of extruder designs:
https://www.thingiverse.com/thing:3752

...and another which is very comprehensive and includes planetary gearboxes,
herringbone bevel gears, in German but I could help with anything Google
Translate doesn't make sense of!
https://www.thingiverse.com/thing:1604369
(apparently sometimes this generates non-manifold issues but I've not yet
had that issue...

Here is an unfinished library that contains good stuff too:
