All 8 OrcaSlicer surface density patterns, printed at 25% / 50% / 75% / 100%. 
Each square is 40x40mm — large enough to clearly see what the pattern does at 
each density level. Print it once, keep it on your desk, never guess again.

WHAT YOU'LL SEE:
- Rectilinear & Aligned Rectilinear: parallel lines, very similar visually — 
 useful as a grip texture from 40-60%
- Monotonic & Monotonic Line: smoother line ordering, cleaner appearance at 
 higher densities
- Concentric: follows the shape of your model, looks great decoratively from 
 25-50%
- Hilbert Curve: labyrinth pattern, most interesting below 50%, slowest to print
- Archimedean Chords: spiral pattern, uniform open look, good for liquid filling
- Octagram Spiral: large open compartments at low density, perfect for 
 epoxy/resin fills

NO MULTI-COLOR PRINTER NEEDED:
Layers 1-6 are your base color. Only layer 7 is different. 
Set a filament change pause at layer 7, swap filament, done.

FILES INCLUDED:
- 8 separate 3MF files (one per pattern)
- 1 combined 3MF with all 4 plates
