3D model descriptionThis 3D model is inspired by the Petzl Elios, a versatile climbing and mountaineering helmet known for its durable construction and adjustable design. The real Elios uses an injected ABS shell paired with expanded polystyrene (EPS) foam to provide strong impact protection while keeping weight reasonable.

3D printing settingsPrint Technology: FDM (for strength) or Resin (for detailed vent flaps)

Material: PLA for ease, or PETG / ABS for a more “authentic feel”

Layer Height: 0.15–0.2 mm for standard parts, 0.1 mm for fine features (vent flaps)

Infill:

Helmet shell: ~20–30%

Vent flaps and clip areas: ~40% to strengthen them

Supports: Yes — especially under vent flaps, the lamp clips, and any overhanging shell parts

Print Speed: ~50–60 mm/s (for FDM)

Bed Temperature: ~60 °C (PLA), ~70–80 °C (PETG)

Nozzle Temperature: ~200–210 °C (PLA), ~230–240 °C (PETG)

Nozzle Size: 0.4 mm recommended, but smaller (0.3 mm) can help fine details on vents
