Feather STL 3dprinted

these files are included in a zip folder (unpack before use):
Presliced gcode for Elegoo Centauri Carbon (PLA)
Orcaslicer profile for print settings (currently only for "MyKlipper" machines in orca, im trying to figure out how to have it show up for all printers)
STL file
The instructions

An alternative approach to making fake feathers! See video at the bottom.
May be printed in any filament (tested with success: PLA, TPU, ABS, PETG, active foaming)
If your slicer warns you about floating regions, ignore the warning.
If you don't use the included Orcaslicer profile, see below for print settings. The setup and settings is similar for Prusaslicer or Bambu. In Cura or other slicers some settings may have a different name or it may not be possible (infill pattern limitations)
The dimensions of the feather are designed for 0.4 nozzle and 0.2mm layer height. If you rescale the feather, or use a different nozzle or layer height, you need to keep these same ratios.
So if you scale the feather 150%, use a 0.6 nozzle and 0.3mm layer height.
If you change these ratios, you may not have a great result but you can play around with the settings below to find a result that works for you.
For example, keeping just your Z-scale at 100% but resizing the X and Y will work too.

Print instructions:
Choose/import Feather print settings in orca (see below)
Load STL
Rightclick STL "Split into objects or parts"
(Ignore warnings about collision)
Slice the STL, check the preview to see the infill direction
Go back to your STL, select the half that has the wrong infill direction
Select "Objects" list, and change the "Sparse Infill Direction" setting in the "Strength" menu to 315 degrees
Slice STL, check preview to see if it looks good.
Change the print settings for the shaft part if you wish. You can print it in a different filament or add extra walls/different settings for strength.
Now you're ready to print.
After the print, peel off the outside line to reveal the feather edge. Sometimes you have to use scissors to cut it off.
Heat the 3dprint to shape the feather if desired.

Critical slicer settings for 0.4 nozzle, 0.2mm layer height.
These are included in my "Feather" print profile for Orcaslicer custom klipper 3dprinter (if you import it with a different printer, it will not show up).

wall generator: Arachne
detect overhang walls: unchecked
walls: 2
top layers: 0
bottom layers: 0
Top/bottom/wall overlap: 80%
Infill/wall overlap: 0% (use a little more if your feather lines dont connect enough with the outside)
Sparse infill density: 99%
Sparse infill pattern: 2D lattice
Sparse infill direction: 45 degrees (change to 0 and 90 degrees if you are rescaling the feather for maximum bed size and you rotate the feather diagonally)

Additional settings and tips to optimize your print for speed/quality:
Seam position: Nearest
Avoid crossing walls: Enabled (also known as combing)
(in filament profile): Disable Z-hop
(in filament profile): Travel distance threshold: 1mm (or greater)
You may want to reduce cooling if the infill has trouble bridging to the outside wall, or increase infill/wall overlap setting.
If you reduce the print infill density to 75%, you can create an ostrich (fluffy) feather, as the lines will not fuse together as much
This print also works well in TPU for a soft feather, but it'll get very floppy.
You can try multi-material to print the shaft in a tougher filament, or glue a spine to the feather.
