Thanks Diego, Automaton and Torsten!
Well, I build fast, because I had to create a new system after getting married. My wife goes to work 2 hours before I go, so I get up together with her and have 2 hours in the morning. So what do you think I do for that 2 hours?

Torsten, I also use a knife to cut and feed the decals into the panel lines and I also did it on this model, but still these decals are really thick.
