This is a spherical function that I thought turned out like a lemon squeezer, but I wouldn't actually advise using it for that purpose. It was created using Functy and is completely defined by the following functions.
Radius = 0.01*((3+(cos(12*(a+(p*2)))*((sin(p)+0.01)**(1.3)))+cos(4*p))*(1-((p/(22/7))**(2.5)))),
(R, G, B) = ((1+cos(p*2))/2, 0.3, cos(12*(a+(p*2)))>0.9).
I've not yet printed it, so I'm afraid I can't guarantee what the result will be like if you decide to print yourself a copy (although I'd be interested to know!)
