Hi monkey_man,

I have modeled more than 150 models to print them and making pendants, rings, earrings. ..
One of the best feature for MOI in this use is Having the status of parts : surfaces and solid !
Solids are printable objets and Moi always give this status.
Nurbs give you opportunities to model easy and fast. Export functions are great too to have stl files.
Test it ! Use it!
