Beautiful work, Mihe :D It had to take much effort to develop such mastery in center - symetrical techniques that you have reached. Its pity that no such things are possible in LDD which I use. Please , dont left LEGO behind, your style is quite unique :D

All those angles must've been difficult, but you've certainly pulled it off.
Thank you ;-) The angles wasn't so tricky - i think the most challenge was to get this thing nearly closed, if the upper part is down. So the wideness of the twelve sections must be correct to the diameter...
