Why doesn't it work like the original?

• It does look very nicely printed, I didn't follow along your previous posts just yet - but what is your printer if I may ask?
  Especially the round shape on the lower end would not look just as round if I had it printed on my old Prusa, I think.
• Do you always use Fusion 360?
  a friend of mine, who is more talented on the physical side of things than the "virtual" details like me, really loves Fusion, but I can't stand being dependent on some companys software - which may any day take whatever they want for it - for my 3d printing needs (somehow it's against the whole idea for me, though I don't mind paying for things in general)
