It should also work with the 0.4mm nozzle.
0.6 and 0.8 are for faster print speeds and higher layer heights.
But I recommend for the "wings" the vase mode with a 0.6 nozzle, layer height 0.3 - 0.4mm.
It might be better to print additional segments (
1xCentersupport + 2xWing ... + 1xshaft ...).
The small version needs a bit more wind than the bigger one.
But you can easily add segments later.
I'm looking forward to your photos! :-)
