Hi Michael,

I was able to apply a .2 Fillet to your 'KleinTeil clipped', but I was not able to separate the 'desired object' from the 'border' cut away, i.e. I could not DELETE the 'border'.

First method: I did HIDE the 'desired object' and DELETEd the 'border', did SAVE AS the 'result', but when I reopened the 'result', the 'original object' appeared.

Second method: I clicked on and EXPORTed the 'desired object', but when I reopened the 'result', the original object appeared.

Is there another method?

Could you please have a look at the second file I originally attached ('KleinTeil rounded').
Here I tried something similar to the clipping you applied, but I could not FILLET nor SHELL this object (filleting would not be required for this object).

Is there a possibility to shell this Object (, which would significantly reduce the cost of the 3D-print)?

thanks & regards
Jurgen
