"The plug V" (as in Vertical) has been designed to celebrate the Kossel printers and their derivatives (such as the Kossel Clear). The Plug is designed to serve as a lamp and mixes two mathematical parametric functions.
The first parametric surface gives the general shape of the lamp. It has been discovered by the French mathematician Jules Tannery (http://en.wikipedia.org/wiki/Jules_Tannery) and is known as Tannery's pear. If you are curious and read French, have a look to the corresponding publication: https://archive.org/stream/s2bulletindessci16fran#page/n195/mode/2up
The second function creates specific Vertical waves on the first surface. It's not a simple sinus function but a succession of half circles (going inside then outside, etc.).
Initially designed as 'The Plug H' (with horizontal waves), the waves have been reoriented as the "H" version seems unprintable on an FDM 3D printer because of extreme overhangs.
Both the H and V version of this lamp should be soon available on Shapeways:

Inside, a 3W GU10 LED lamp illuminates the surface.
