This Fallout-inspired Robobrain model is a retro-futuristic desktop prop designed to evoke the eerie charm of a broken-down pre-war relic. Printed in PLA and TPU, it features articulated, print-in-place arms reinforced with 2.5mm–3mm aluminum sculpting wire, allowing for dynamic posing without compromising durability. The tread assemblies are secured using M2×3×3mm heat-set inserts, ensuring a clean, modular build that’s easy to assemble and repair.

The aesthetic leans heavily into post-apocalyptic decay: the body is scuffed and battle-worn, with deliberate imperfections that suggest long-term exposure and mechanical fatigue. Most striking is the green-stained dome, a visual storytelling element that implies the Robobrain’s biogel containment ruptured, oxidizing on contact with air and permanently tinting the dome — a subtle nod to the lore of compromised Institute tech.

This model blends functional articulation with narrative-driven design, making it ideal for collectors, Fallout fans, and makers who appreciate props that feel like they’ve lived through the wasteland.

Assembly tips:

To attach TPU arm sleeves to shoulder joint put two small drops of glue into slit in shoulder part and then insert the sleeve and hold.

The arm ends are keyed for the shoulders and claws, so if they don't fit flip them around.

Note: The treads are not designed to move. Do not force the arms to bend past their limitation or they can break with or without the internal wire. I do recommend to use 2.5 or 2.75mm diameter aluminum sculpting wire. Three millimeter wire will work but will limit flexibility. The wire is only really there to give poseable support and not reinforce the structuring.
