That's exactly what I needed, could not be better.
I make this Screw Conveyor and for me is look OK, I got just few problems.
If I make a tube, and I want to put helix in that tube, I cant. This would save me the time with settlement of the pipe axis, and scale Conveyor to adjust inside teh pipe.
But I'm still happy
Thank you all for support.
I apologies, it has word zmrzlina in slovenian
But allmost no one use this word anymore, I found word only in few old recipes for candy. So you were right, again
