+# Blender-Workflow — RACI-Konsolen-Board
+
+Besserer Look als OpenSCAD: weiche Fasen (Bevel), smooth shading, optional Relief,
+schöne Vorschau-Renders — und trotzdem **maßhaltig** (alle Mulden/Passungen im Skript).
+
+## Tooling
+- **Blender** (gratis): https://www.blender.org/download/ (4.2 LTS empfohlen).
+- Generator-Skript: [`raci-board.py`](raci-board.py) — baut das Board parametrisch.
+
+## So baust du das Board
+**Variante A — in der Blender-Oberfläche (empfohlen zum Iterieren):**
+1. Blender öffnen → oben Reiter **Scripting**.
+2. **Open** → `raci-board.py` → **Run Script** (▷).
+3. Das Board wird erzeugt (gerundete Kanten via Bevel). Im **Layout**-Reiter ansehen.
+4. Export: `File → Export → STL` (bzw. 3MF für den H2D, falls Addon aktiv).
+
+**Variante B — headless (nur Datei erzeugen):**
+```
+blender -b -P raci-board.py
+```
+→ legt `raci-board.stl` (+ Vorschau `raci_preview.png`) neben dem Skript ab.
+
+## Maße (Spec — der „Vertrag", gilt in jedem Tool)
+| Element | Wert |
+|---|---|
+| Board | 210 × 210 × 10 mm, Außenkanten gefast (Bevel ~1,2 mm) |
+| Acryl-Chip-Mulde (Mitte) | Ø **40,6** × Tiefe **1,8** mm (+ Greifkerbe Ø12) — für Chip Ø40 × 2 mm |
+| Figuren-Sockel-Mulden | **10×** Ø **25,3** × Tiefe **1,5** mm (Sockel Ø24,5) |
+| Sockel-Ring-Radius | 48 mm (Mitte–Mitte), 36° Teilung |
+| RACI-Sektoren | **R 3 · A 1 · C 4 · I 2** (= 10), Trennstege erhaben |
+| Sektor-Beschriftung | groß **R/A/C/I** + Wörter RESPONSIBLE/ACCOUNTABLE/CONSULTED/INFORMED |
+| Action-Card-Halter | Steh-Schlitz **63 × 4 mm**, ~12° nach hinten geneigt (Karte 60×90) |
+| Druck | 6× in Phasenfarbe (5 Phasen + Gate-Rot), einfarbig je Board |
+
+## „Edel" machen (manueller Feinschliff in Blender)
+Nach dem Skript-Lauf für den Premium-Look:
+1. **Smooth shading:** Objekt wählen → Rechtsklick → *Shade Auto Smooth*.
+2. **Mehr/Schärfere Fasen:** Bevel-Modifier-Breite/Segmente erhöhen, oder Kanten markieren
+   (*Edge → Mark Sharp/Crease*) und Bevel nach Winkel/Weight.
+3. **Relief/Thema (optional):** flaches Stadt-/Platinen-Relief als Bild → *Displace*-Modifier
+   mit einer Textur auf einer Unterteilungsfläche; oder Mikro-Rillen im Mittelfeld.
+4. **Typo schöner:** eigene Schriftart laden (Text-Objekt → Font), Bold, leicht erhaben
+   statt graviert.
+5. **Export:** STL (mm) für den Slicer; Wandstärke/Mulden vorm Druck einmal prüfen.
+
+> Das Skript ist ein **Startgerüst v1** — sag mir nach deinem ersten Lauf, was hakt
+> (Version/Fehlermeldung), dann fix ich es gezielt.
