Description

Rocky the Eridian - Project Hail Mary

Bring everyone's favorite alien engineer to your desk! This model captures Rocky, the brilliant Eridian from Project Hail Mary. Designed with his biologically accurate pentaradial (five-sided) symmetry, this figure features his thick, rock-like carapace and five limbs, with one raised in a friendly Eridian greeting (or perhaps asking a question!).

The slightly faceted, low-poly design gives the carapace a great textured, rocky look that catches the light beautifully and prints cleanly.

Model Features

  • Accurate Anatomy: Features the central carapace and five multi-jointed limbs.
  • Dynamic Pose: Stands entirely on its own with one limb raised.
  • Great for Desk Display: Perfect size for a companion while you work on your own engineering problems. Amaze!

Recommended Print Settings

  • Material: PLA or PETG work perfectly for this. A matte or marble filament would look incredible for his rock-like texture.
  • Layer Height: 0.16mm or 0.20mm to capture the geometric facets of the shell and joints.
  • Infill: 10% - 15% is plenty (Lightning or Gyroid recommended).
  • Supports: Yes. You will need supports for the underbelly of the carapace and the raised arm. Snug or organic/tree supports are highly recommended for easy removal without scarring the legs.
