Neuronauts — 3D-printable standees

Flat relief standees of the five Neuronaut characters (Captain Cortex, Axon, Dendra, Syn, Glia), generated directly from the character coordinates used in neuronauts/index.html. Each figure includes the neuron-styled details from the page art: the trailing axon-cable tail with myelin beads and a glowing synaptic bouton, plus a raised chest emblem, eyes, and mouth.

Files

• neuronaut-cortex.stl, neuronaut-axon.stl, neuronaut-dendra.stl, neuronaut-syn.stl, neuronaut-glia.stl — one figure each, ~45 mm wide × 84–94 mm tall × 4.5 mm thick, each on its own integrated base plaque.
• neuronaut-all-five.stl — all five arranged side by side on one plate (264.8 × 93.6 × 4.5 mm), ready to slice as a single print job.
• generate_stl.py — the generator script (Python + shapely + trimesh). Re-run it after editing the character geometry in neuronauts/index.html to regenerate matching STLs; see the constants at the top (SCALE, BASE_MM, DETAIL_MM, PLAQUE) to adjust size or proportions.

Design

Two-layer relief, extruded from the flat SVG artwork:

• Base layer (3.2 mm): the full body silhouette — legs, boots, torso, arms, gloves, helmet, head, hair, and the axon-cable tail — fused to a rounded rectangular base plaque so each figure stands with no supports.
• Detail layer (+1.3 mm on top): the chest emblem, eyes, and mouth, for a painted-relief look.

Print settings

No supports or brim needed — every figure has a flat bottom and a wide, stable base plaque. Suggested starting point for FDM:

• Layer height: 0.12–0.16 mm (captures the emblem and facial detail best)
• Infill: 15–20 % is plenty at this thickness
• Orientation: print flat, base plaque down, as-is
• Nozzle: 0.4 mm; hand-paint the raised details after printing for the full multi-color look from the page

For resin printers, print upright (rotate 90° so the base plaque is a vertical wall) for the cleanest surface finish on the face.
