Yes! I've been thinking about the same, but you're clearly way ahead  
of me.
If you provide metric nuts and bolts as well, it would be awesome. We  
might also want to ship your library with OpenSCAD if it turns out  
well and you permit it.

Since OpenSCAD doesn't really provide a full programming language  
(e.g. iteratively building an array is not allowed), your approach is  
probably the most reasonable atm.

Talking about Open Inventor, I've been considering integrating Coin3D  
into OpenSCAD. It has potential for making the rendering code a bit  
cleaner. It is, however, a pretty large dependency to drag in. In  
addition, I fear it will be a little hassle making OpenCSG work well  
with Coin3D. 3D font support might be the tipping point for dragging  
in another external library though, so let's see..
