I need something that openscad can handle. You could take OpensCAD out of the loop, I suspect, and print the gears from the stock part models from (for example) McMaster Carr Or you could tell me the centres, tooth size and PCD you need and I can send back a model from Inventor in not much time. But why use spur gears? One thing that 3D printing is good at is double helicals. Or even triple, or quad. But those are stupid: https://images.app.goo.gl/ZbZBVWoBEnRbPL469 Note, these are a daft idea. But I have actually seen a 9 foot diameter triple helical in my dad's old workplace. He did need to explain to me why it was silly, and why they refused to replace it and specced a double instead. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
