Printed fine, look good. Unfortunately it does not work, no tone. (Yes I do know how to operate these toys. I have used them a lot during my youth...)

@Henk hmm, strange. Nice finish tho! For me they work as espected. Are you sure there's enough space for the air to travel fom the nose hole down to the half circle hole?
@Cson Hallo Son, Yes the air flows freely in the right direction. I suspect that the "sharp edge" that normally creates the tone is not "sharp" enough. It is pretty rounded. This might have been caused because I sliced the stl for my MK4 with "input shaper". I will try what will happen when I slice it without input shaper.
