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.

Amase amase amase! These came out awesome I used a sandstone PLA for mine to give him and even better rock look. I tried printing it with my smooth plate first and the legs had a bit of trouble staying on the build plate but when I switched to my textured plate it worked great

tried twice on my P2S with Bambu PLA and om both times the legs fell down during the print. tried the same print and PLA with my A1 MINI and it worked. looks really good!

@slowjabroni

same. the legs need better supports. useless model otherwise it will break half way through when the legs pop off the bed.

I printed this out with Elegoo PLA Marble Cement Gray. One of the arms fell off mid-print but I was able to work with it. Overall I like the attention to detail.

The designer has replied

@eminozcelik

sorry to hear that! i tried to make the connections as strong as possible without giving up from details but this was max I could do. I’m glad you worked it out and enjoy!

It’s no worry at all. It gave me an excuse to use my mini drill 😊
