Print Settings

Layer Height: 0.1–0.16 mm → finer layers will capture the etched details and crisp angles.

Wall/Perimeter Count: 3–4 → gives good durability for a small item.

Infill: 20–40% → grid or gyroid; higher if you want it to feel heavier and more solid.

Top/Bottom Layers: 5–6 → ensures smooth, strong surfaces.

Print Speed: 40–60 mm/s → slower helps capture fine geometry.

Supports: Not needed if oriented flat (both front and back prints face-up).

Material Choice

PLA+ or PETG for easy printing and toughness.

ABS or ASA if you want sanding, vapor smoothing, or painting (cyberpunk “metallic” look).

Consider dual-extrusion or pause & swap filament for glowing circuit lines (fluorescent or glow-in-the-dark filament).

Post-Processing Ideas

Paint grooves with neon acrylic or resin fill for that glowing cyberpunk vibe.

Spray coat with matte black primer, then hand-paint highlights with metallic silver or chrome.

Optionally embed a tiny LED and coin cell if you want a light-up effect (though trickier).
