The front view:
The left side view:
The conspicuous vertical lines come from the 0.10 infill honeycomb; there are no visible retraction zippers and the surface is smooth to the touch.
A closeup of the beak shows the crystal-clear drooping filament; a similar effect happened on the downward-pointing feather tips. Generally, this is a sign of too-hot extrusion, but at 165 °C I’m not convinced that’s applicable. It may simply be too much overhang at this scale:
Overall, it’s pretty good. The config info doesn’t include the external perimeter speed, which I’ve been dialing back from an insanely high value. I think it was 75 for this one, which might be flinging the filament off the edge of the beak below that steep overhang.
