# SolidCraft flat-pack sheet metal (extends solidcraft-sheet-metal)

Load `solidcraft-sheet-metal` first for the base commands. This skill adds the flat-pack method learned on a CD-ROM player enclosure (the das_POD CD-ROM Player 01, second version of the model). Send several screenshots from different views, keep one folder per model and name changes `_v2`.

Background material is in `references/`:
- [`references/flat-pack-dfm-and-bend-formulas.md`](references/flat-pack-dfm-and-bend-formulas.md): design rules for slits, bridges and tabs, bend formulas and K-factors.
- [`references/cdrom-player-das-pod-analysis.md`](references/cdrom-player-das-pod-analysis.md): architecture and dimensions read from the maker's assembly video, and what the reference build did.
- [`examples/cdrom-player-flatpack/`](../../examples/cdrom-player-flatpack/README.md): the two CD-ROM player models (3MF and SolidCraft design files). v1 folds tall walls straight from the base. v2 uses large folded panels with round ear tabs at the screw locations.

## 1. Read the architecture first
- A flat pack is a few flat sheets: 2 main plates joined by a perforated or slit bend line, 2 separate side plates and hardware. Side plates are NOT folded from the base. Check the real flat patterns or photos before modelling: the first version of the CD-ROM model was wrong because the walls were assumed instead of read.
- Typical set: BASE sheet (rear plus bottom), LID sheet (top plus front), 2 side plates, rear panel, fasteners (M3/M4 plus nut), feet, placeholders for internals.
- Dimensions taken from video frames or photos carry about +-8-10 %. Say so. Spoken numbers are unreliable. Use a known part as the scale (a 5.25" drive bezel is 148 mm wide).
- If real flat patterns are supplied later, diff them against the model list: perforation, windows and grids, steps, ear count and positions, feet and fan holes, relief notches, part count.
