Cabinet Builder

Design a plywood drawer cabinet, look at it in 3D, and get the cut list.

• cabinet.py – the engine (pure Python, no dependencies). Works on the command line and in the browser.
• src/template.html – the page: inputs, three.js 3D view, tables.
• build.py – pastes cabinet.py into the template and writes index.html.
• index.html – the built site. This is what GitHub Pages serves.

In the browser the Python code runs with Brython (loaded from jsDelivr), so no server is needed.

Run locally

python cabinet.py                      # example cabinet
python cabinet.py example-config.json  # your own config
python build.py                        # rebuild index.html after editing cabinet.py or the template
python -m http.server                  # then open http://localhost:8000

Host on GitHub Pages

1. Create a repository and push these files (at least index.html).
2. Repository → Settings → Pages → Source: Deploy from a branch, branch main, folder / (root).
3. The site appears at https://<user>.github.io/<repo>/ after a minute.

Always run python build.py and commit index.html after changing cabinet.py.

Construction rules

• Outer side panels run the full height; top, bottom and shelves fit between them.
• A shelf between rows is one continuous piece across the inner width.
• Column dividers sit between two horizontal panels, sunk sink mm into a dado in both (length = opening height + 2 × sink). Columns in different rows need not line up.
• Optional back panel covers the full back; carcass depth = depth − back thickness.
• Drawers are built like the carcass: opening minus the margin on every side and at the back; the sides run the full height and depth, the bottom fits between the sides, and front and back fit between the sides on top of the bottom.
• Materials: plywood you already have is filled first; the rest goes on new sheets (what you need to buy). Packing is a simple guillotine layout, so treat it as an estimate.
• Nails: glue plus one nail every nail_spacing mm (default 100) along each joint, at least 2 per joint; +10 % spare in the shopping total.

Config

Sizes in mm. stock is a list of {"thickness", "length", "width", "count"} for plywood you already own. Row height and widths accept auto or numbers; widths is a comma-separated list per drawer ("300, auto").
