Druck funktioniert ohne Probleme, die hälften habe ich mit UHU Hart Modellkleber verklebt. Die Lager gehen sehr schwer rauf und ist etwas zu lange für d drehen nicht ordentlich
A suggestion for how to make the printing/assembly of this model better, would be to have the end parts printed separately, and inserted like pins, and have the roller cut in half at the middle, and you print the two halves standing upright, and have a 3rd pin to put the two ends together.
Edit:
I've thrown together a remix here:

prints perfectly. I printed in petg. glued together perfectly and functioned flawlessly. just installed so I don’t know. about longevity but I am so far very happy.
