An AI-agent operating system for Blender 5.2 LTS: skills, a verified knowledge base, an execution contract, and a production gate — built so an agent (Claude Code, Codex, Google Antigravity, or any MCP client) can model, rig, animate, render, and ship 3D-printable, dimension-correct parts rather than pretty demos.

Everything here is Blender-native: no vendor mesh generation, no downloaded assets, no paid model calls.

🎞️ Product tour

The 24-second loop pairs overview and detail frames from four native Blender builds: robot arm, watch-winder capsule, wellhead, and separator. Frame labels state the evidence scope; it is not a physical, manufacturing, pressure, thermal, or performance claim. Static fallback poster · Source and output provenance.

🧭 What is inside

🔬 Proof: the robot arm is real geometry, not a picture

The model open in Blender 5.2.0 — scene A5-Original-refined, 671 objects, frame 3031/3031, outliner and properties visible (full-window screenshot, not a viewport crop)	Six-angle Cycles orbit of the assembled parts at the final frame, rendered headless from the shipped .blend
Render tessellation of the 402 arm part meshes (114,723 polygons), Cycles Wireframe node — every edge you see is in the file	38 fit-prototype parts arranged on five 220×220 mm plates (PETG + TPU), exported as STL/3MF

Cycles render of the assembled model at the final frame (1600×1200, 96 samples, Metal). The full-speed MP4 of the assembly film is in builds/robot-arm-original-refined/video/.

Production gate run on the real print kit (2026-09-06). The 38 exported STLs were re-imported into a metre-scaled scene and gated against a spec generated from parts-list.csv (target dimensions ± 0.1 mm, one shell per part, PETG/TPU):

GATE PASS | 38 part(s), 0 failing check(s) | scene=72ab501e47bf spec=d88bc836fb3a | Blender 5.2.0 LTS
836 checks pass · 0 fail · 38 skip (no min_wall_mm declared) · 38 info (overhang reported, not gated)

Per part: non_manifold_edges, non_contiguous_edges, wire_edges, loose_verts, zero_area_faces, self_intersection_pairs, shells, signed_volume_positive, bbox_dims_mm, scale_applied, scene_unit_system, scene_scale_length, then STL round-trip repeats of the topology and dimension checks. Report, spec and the reproduction script: builds/robot-arm-print-assembly/reports/gate-report-260906.json, gate-spec-260906.json, scripts/gate-import-parts.py. The report's exclusions say what this does not prove: load capacity, print success, assembly fit, thermal/creep — those remain physical evidence, and the arm stays unreleased for manufacture.

🏭 ORC workflow demo

The ORC component workflow, brief template, and Separator worked example show how a reference-driven component moves from coverage and interface contracts to object-level evidence and bounded review.

The 24-second component tour uses native review media and bounded family studies. Wellhead and separator owner appearance review remains pending; bellows R2 is a form-approved reusable pilot; the RTD/PT images are form studies, not a final exchanger-train claim.

Completed render-only Separator component: overview.	Completed render-only Separator component: a critical crop used to inspect the vapor nozzle, flange, and attached instrument.

Form-approved reusable bellows-family pilot. Exchanger-train detail, a full plant, print readiness, and manufacturing qualification remain out of scope.

The three images are compressed derivatives of native Blender renders, not source references. Provenance records the source and output hashes plus the evidence scope.
