OpenSCAD를 사용하여 프로그래밍 3D CAD에 대한 Claude Code 기술. 디자인, 미리 보기, iterate, STL에서 재구성, 그리고 3D 인쇄할 수 있는 모형 - AI 몬 시각적인 의견 및 자동화한 메시 비교로.

특징

• ** 빠른 모드 ** - "I need a spacer"에서 렌더링 된 부분에 한 라운드 여행 : 가정은 추측된다, 다음 앞에 묻는 대신 다시 나열 -Modify 모드 — booleans (import()] + cut/add/trim)를 가진 기존의 STL를 수정하지 않고, -Printer Calibration — Clearances는 1개의 측정된 단면도에서, 그래서 3의 대신 첫번째 인쇄에 부분 적합
• **Programmatic 3D 모델링 ** - .scad 자연적인 언어 묘사에서 파일 생성
• **AI 비전 피드백 루프 ** - 다중 각도 PNG 미리보기를 렌더링하고 결정적으로 refine 디자인 분석
• **STL-to-SCAD 재구성 ** - SVG 프로파일링 및 SDF 최적화를 사용하여 기하학 OpenSCAD 코드로 역설계 STL 메쉬
• **Image-to-CAD 복제 ** - 참조 사진에서 물리적 개체를 재현 -Parametric design - CLI [T2] 플래그를 통해 과도한 변수로 모든 차원

OpenSCAD Claude Code Skill

A Claude Code skill for programmatic 3D CAD using OpenSCAD. Design, preview, iterate, reconstruct from STL, and export 3D-printable models — with AI-driven visual feedback and automated mesh comparison.

Features

• Quick mode — One round trip from “I need a spacer” to a rendered part: assumptions are guessed, then listed back explicitly instead of asked for up front
• Modify mode — Edit an existing STL with booleans (import() + cut/add/trim) in minutes, without reconstructing it
• Printer calibration — Clearances descend from one measured profile, so a part fits on the first print instead of the third
• Programmatic 3D modeling — Generate .scad files from natural language descriptions
• AI vision feedback loop — Render multi-angle PNG previews and analyze them to iteratively refine designs
• STL-to-SCAD reconstruction — Reverse-engineer STL meshes into parametric OpenSCAD code using SVG profiling and SDF optimization
• Image-to-CAD replication — Reproduce physical objects from reference photos
• Parametric design — All dimensions as variables, overridable via CLI -D flags
• Mesh comparison — Boolean diff rendering and IoU scoring to verify reconstruction accuracy
• Printability analysis — Wall thickness, overhang, and manifold validation
• Reusable module library — Common 3D printing patterns (counterbores, heat-set bosses, ribs, snap-fits)
• Eval framework — Automated testing with 20 binary assertions across 4 scenarios (100% pass rate)

Prerequisites

OpenSCAD, reachable from the CLI. Every script resolves it as $OPENSCAD_BIN, else command -v openscad — no path is hardcoded.

sudo pacman -S openscad     # Arch / Omarchy
brew install openscad       # macOS
sudo apt install openscad   # Debian / Ubuntu

Python packages, needed only by Reconstruct and Replicate. Quick, Modify, Design and Export work without them.

# Arch: install from the repos, the interpreter is externally managed and pip will refuse
sudo pacman -S python-trimesh python-numpy python-scipy python-shapely python-rtree

# macOS / other
pip3 install trimesh numpy scipy rtree shapely

Claude Code CLI installed.

Calibrate the printer, once

Clearances are the difference between a part that fits and a reprint. Print templates/calibration-comb.scad one time, measure it, and write the numbers into templates/printer-profile.scad. Until profile_measured is set to true the skill uses declared defaults and says so whenever it emits a part whose function depends on a fit.

Installation

Option 1: Clone and symlink (recommended)
