Parametric cup silver

silver is an homage to Netscape versioning.
I wanted to make a cup with extremely thin walls.
I have yet to try and print this. Therefore no images.
And I will not print it until I find a beautiful way to put an ear on the cup.
Added an ear to the cup. And some other improvements. Damn hard to rotate and place the ear correctly in a parametric way...
Feel free to use as you wish.
Yeah almost forgot, I can't be blamed for other's stupidity.
