All right. Now I dumped the whole shell attempt and duplicated the object, scaled it and did a boole. Result looks fine and calculation is way faster than "shell". So on to the next question: how can I bevel the upper edges via "filet" since I havent got continuus edges/splines I could select...

Thanx for your patience with me so far :-)
