+** Customizing
+
+The built-in customizer in openscad can be used to easily tweak
+settings. A few presets that I used are included.
+
+** Print orientation
+
+Use Cura or Slic3r "align to face" feature to lay the mouth of the
+horn on the print bed.
+
+** Print Settings
+
+Intended to be printed hollow:
+
+ - 0 bottom layers
+ - 0 top layers
+ - 0% infill
+ - 0.2mm or lower layer height
+
+Did not have great luck with vase mode @ 0.2mm layer height (overhang
+near end of horn was too great and there were gaps), but might be
+worth a shot at 0.1mm.
+
+*** PETG
+
+Using a prusa mini with a 0.4mm nozzle @ 0.2mm layer height, I needed
+six perimeters to make the horn watertight. Also needed to make the
+final 10-15mm of the horn solid.
+
+** Guidance on making model watertight
