Purpose
I wanted the original tooling formulas to be immediately usable while preserving a controlled path to manufacturing-ready exports.

Rocket Tool Sketcher
Parametric rocket-tooling drawings and manufacturing export bundles in the browser.
Case summary
System
Rocket Tool Sketcher is a browser-based designer for spindle and rammer tooling. It turns tube size and manufacturing tolerances into an annotated drawing and downloadable review/CAD artifacts.
Contribution
Product flow, parametric geometry/tolerance behavior, browser-to-export service boundary, manufacturing artifact acceptance criteria, and deployment verification.
Design-to-artifact flow
Geometry and export generation are deterministic; the service boundary keeps CAD generation behind the deployed application.

Problem
- Tooling formulas are useful only when they are easy to inspect and turn into manufacturing artifacts.
- Export services should remain behind the deployed application boundary.
Technical Highlights
- Interactive spindle and rammer drawings
- Preset/custom sizing in inches or millimetres
- Manufacturing tolerances and clearance checks
- PDF, DXF, STEP, STL, OpenSCAD, and JSON export artifacts
- Python CAD exporter behind the web application
System Design
- React/TypeScript designer creates a validated tooling model in the browser.
- Nginx proxies only export requests to the internal Python CAD service.
- Jenkins runs tests, browser smoke checks, and deployment.
Deterministic Authority
- Tooling formulas, tolerances, validation, and export generation
Where Models Fit
- No model is required for the core design/export workflow.
Trust, Failure & Recovery
- Export API is not independently exposed as a public service.
