@ Xtreme Addict: Thanks a lot
@ jurek: That would lower the price by like 3 EUR The deep, 10mm wide structure is the biggest problem here. If you create a simple pot with 4 holes it will take 2 minutes to drill them and you're done. This structure takes about 25 minutes on a expensive machine. Also the aluminium bottom part is expensive for such a small thing because it's laser-cut, machined to get a perfect surrounding and brushed for a good look. Afterwards a black anodizing.
