Long Spiral Nautilus

A work in progress, kinda pushing the limits of what 123D Cad can handle, it seems. I haven't printed one yet, so let me know if you do! Each section is 1.611 X bigger that the previous, so you can copy and scale to make a long shell. Future plans are for a spiral amplifier tube for a phone, maybe, or a crazy vuvuzela, or maybe a drill attachment for a robot,etc.

More to follow on this...
