This remix for ABS printing I've made after struggling with original design.
Here are lot of gluing for each wing, but quality is much better, than print_as_one-piece.
Printer:
Wonwall
Rafts:
No
Supports:
Yes
Resolution:
100-150 um
Infill:
100%
Notes:
40 degrees support overhang angle for backbones is highly recommended.
And support interface (in cura 2.4 or higher)
support infill = 20% zigzag
support interface = 80% circle, 1.5mm
support top distance = 1 layer height
Here I need two metal pin in each wing, to connect main body to main wingbones and to connect wingbones to wing palms.
I used to drill that pieces with 1.2mm and 2.5mm drills.
and found equal nails (delete heads off) and insert for stronger structures after gluing.
