Fermat's spiral

Based on Fermat's spiral with Fibonacci sequence, I created this
model using 3D Studio Max with Maxscript and fixed afterwards with Magics, so the file is 100% clean and ready to print.

I made it with 60 mm diameter, so it won't take too long to print and it will look nice on your table.

I might create variations upon request or sugestions.
If you print, don't forget to upload :)
