+# 3D-Druck — Übersicht
+
+Alles, was der 3D-Druck-Producer braucht, um die haptischen Spielelemente zu
+fertigen. Großflächige Grafik (Aufdrucke, Beschriftungen) wird **nicht** gedruckt,
+sondern als Aufkleber/Print-Layout aufgebracht — die 3D-Teile liefern Form,
+Verankerung und Steckmechanik.
+
+## Inhalt dieses Ordners
+
+| Datei | Zweck |
+|-------|-------|
+| [`materialliste.md`](materialliste.md) | Alle Bauteile mit Maßen, Mengen, Material- und Druckempfehlung |
+| [`visual-prompts_3d-producer.md`](visual-prompts_3d-producer.md) | Bild-Prompts als Orientierungs-Renderings für den Producer |
+| [`board-layout.svg`](board-layout.svg) | Maßstäbliche Layout-Skizze des gesamten Boards (exakt 40 Tiles, Sequenz, Loop) |
+| `board-layout.png` | PNG-Vorschau der Layout-Skizze |
+| [`gen_board_layout.py`](gen_board_layout.py) | Generator-Skript für die Layout-Skizze (bei Änderungen erneut ausführen) |
+| [`openscad/`](openscad/) | Parametrische Modelle (OpenSCAD) der Schlüsselteile zum direkten Slicen |
+
+## Grundsätzliche Design-Entscheidungen
+
+- **Modulares Tile-System** statt eines großen Boards — jedes Teil passt auf ein übliches Druckbett (≥ 200 × 200 mm).
+- **Lineare Bahn** (kein Ring) — Tiles werden zu einer durchgehenden Linie aneinandergereiht, bei Platzmangel mäandrierend.
+- **Eine standardisierte Verankerung** (Ø 50 mm Rundsockel) für *alle* Plättchen und für den Action-Stein → Teile sind austauschbar.
+- **Steckverbindungen** (Puzzle-Tabs) zwischen Tiles, damit die Bahn stabil zusammenhält und flexibel gelegt werden kann.
+- **Materialempfehlung:** PLA für Tiles/Plättchen/Gates (formstabil, günstig), PLA + Gewichtseinlage (M8-Mutter) für den Action-Stein (Standfestigkeit mit aufrechter Karte).
+
+## Drucker-Annahmen
+
+- Bauraum mind. 220 × 220 × 220 mm.
+- Düse 0,4 mm, Schichthöhe 0,2 mm.
+- Beschriftungen werden als **vertiefte Gravur** (negativ, 0,6–1,0 mm tief) modelliert, alternativ als aufgeklebtes Label.
+
+> Alle Maße sind ein **Start-Spec** und vor der Serienfertigung an einem
+> Funktionsmuster zu prüfen (insb. Passung Sockel↔Plättchen↔Stein und
+> Kippstabilität des Steins mit Karte).

+# Materialliste — zu druckende Elemente
+
+Stand: 2026-05-27 · Maße in mm · Mengen für **ein** Workshop-Set.
+
+## Standard-Schnittstelle (für alle Teile gültig)
+
+- **Verankerung (Sockel):** zylindrische Vertiefung **Ø 50 mm, Tiefe 4 mm**, mit
+  0,4 mm Spielpassung. Sowohl Aktivitätsplättchen als auch der Action-Stein-Fuß
+  passen hinein.
+- **Tile-Steckverbindung:** Puzzle-Tab **12 mm breit, 6 mm tief**, mittig je Kante.
+- **Figuren-Steckplatz:** Pin-Loch **Ø 4,2 mm, Tiefe 4 mm** (für Figuren-Pin Ø 4,0 mm).
+  Einheitlich am **Aktiv-Feld** und an den **Gate-Toren** — jede Figur passt überall.
+
+---
+
+## 1. Phasen-Basistiles (lineare Bahn)
+
+| Merkmal | Wert |
+|---------|------|
+| Grundfläche | 100 × 100 × 6 mm |
+| Verankerung | zentriert, Ø 50 × 4 mm |
+| Kanten | Puzzle-Tabs (Tab/Slot abwechselnd) |
+| Farbe | je Phase (blau/orange/grün/teal/lila) |
+| Menge | **40** (eine je Lifecycle-ID: 37 Aktivitäten + 3 Gate-Positionen) |
+| Material | PLA, Infill 15 % |
+| Druckzeit | ~1,5 h/Tile |
+
+> Tiles bleiben bewusst **clean** (nur Verankerung + Tabs). Die Rollen-Platzierung
+> übernimmt das mobile **Aktiv-Feld** (Abschnitt 4a), das neben dem Action-Stein steht.
+
+Alle Tiles sind **gerade** und werden zu einer **linearen Bahn** aneinandergereiht
+(kein Ring). Bei Platzmangel kann die Bahn mäandrierend (Zeilenumbruch) gelegt
+werden — die Puzzle-Tabs erlauben auch 90°-Ecken.
+
+## 2. Aktivitätsplättchen (einseitig)
+
+| Merkmal | Wert |
+|---------|------|
+| Form | Rundscheibe Ø 49 × 4 mm (passt in Verankerung) |
+| Gravur | **einseitig: ID + Kurzbezeichnung** (z. B. `op_05 — Überwachen der Services`). Rückseite leer/Phasenfarbe — Erklärung liegt in der App |
+| Griff | umlaufende Fase 1 mm zum leichten Herausnehmen |
+| Menge | **37** (eine je Aktivität; an den 3 Gate-Positionen steht stattdessen ein Gate-Tor) |
+| Material | PLA, je Phase eingefärbt (matcht Tile) |
+
+> Plättchen bleibt entnehmbar: beim Bearbeiten herausnehmen und den Action-Stein
+> in die Verankerung stellen („wir sind hier"). Die ausführliche Auflösung kommt
+> über die Companion-App, nicht über eine Rückseiten-Gravur.
+> Bei zu kleiner Schrift für Gravur: glatte Scheibe drucken + bedrucktes Label aufkleben.
+
+## 3. Action-Stein (Szenario-Träger)
+
+| Merkmal | Wert |
+|---------|------|
+| Fuß | Ø 49 × 5 mm (sitzt in Verankerung) |
+| Körper | Zylinder Ø 35, Höhe 30 mm |
+| Kartenschlitz | Breite 74 mm, Tiefe 4 mm, Höhe 25 mm (für Karte 70 mm breit) |
+| Gewichtseinlage | Aussparung für M8-Mutter im Fuß (Kippschutz) |
+| Stabilitäts-Option | zusätzlicher Standring Ø 70 mm, falls Karte zu kopflastig |
+| Menge | **1–2** |
+| Material | PLA, Infill ≥ 40 % + Metalleinlage |
+
+## 4. Gate-Tore
+
+| Merkmal | Wert |
+|---------|------|
+| Form | Bogen/Tor, lichte Weite 90 mm, Höhe 100 mm, Materialstärke 8 mm |
+| Standfüße | 2 × Grundplatte 30 × 60 mm, überspannt 2 Tiles |
+| Rollen-Steckplätze | Lochreihe **Ø 4,2 mm** an der Basis (für Figuren-Pin), 4 Plätze, Pitch 8 mm |
+| Kartenschlitz | oben quer, Breite 65 mm, Tiefe 3 mm (Gate-Beschreibungskarte) |
+| Gravur | „Gate 1/2/3" + Gate-Keeper |
+| Menge | **3** |
+| Material | PLA, Infill 20 % |
+
+## 4a. Aktiv-Feld (RACI-Stecklochleiste)
+
+Mobile Leiste, die **neben dem Action-Stein** steht und mit ihm weiterwandert.
+Hier werden die je Aktivität beteiligten Rollen-Figuren nach **RACI** gesteckt —
+RACI wird so **pro Schritt** sichtbar, ohne die Tiles zu verändern.
+
+| Merkmal | Wert |
+|---------|------|
+| Grundkörper | ~86 × 26 × 6 mm (Länge ergibt sich aus den Zonen), Ecken r3 |
+| Zonen | **R** (2 Plätze) · **A** (1 Platz) · **C** (3 Plätze) · **I** (3 Plätze) |
+| Steckplätze | Ø 4,2 mm, Tiefe 4 mm, Pitch 8 mm (für Figuren-Pin Ø 4,0) |
+| Gravur | Zonen-Buchstaben R / A / C / I vorne, Tiefe 0,8 mm |
+| Menge | **1** (ggf. 2 bei parallelen Tischen) |
+| Material | PLA, Infill 20 % |
+
+> **A = genau 1 Platz** — bildet ab, dass je Aktivität genau eine Rolle
+> *Accountable* ist (RACI-Regel aus `spm_rollen.yaml`). Nicht jeder Platz muss
+> belegt sein; die Leiste ist großzügig ausgelegt.
+> Optional: Rastnase, damit die Leiste an den Action-Stein-Fuß andockt.
+
+## 5. Rollen-Figuren
+
+| Merkmal | Wert |
+|---------|------|
+| Form | Schlanker Pöppel, Höhe ~22 mm, **Standfuß-Pin Ø 4,0 mm × 4 mm** (passt in Aktiv-Feld & Gate-Loch Ø 4,2) |
+| Standfläche | schmal (~8 mm), damit mehrere Figuren in einer Zonen-Reihe nebeneinander stehen |
+| Codierung | Farbe + Formvariante je Rollenkategorie |
+| Menge | siehe `../02_Spielfiguren/` (Governance, Management, Teams) |
+| Material | PLA, eingefärbt |
+
+## 6. Entscheidungs-Chips (optional 3D statt Karte)
+
+| Merkmal | Wert |
+|---------|------|
+| Form | Münze Ø 30 × 4 mm, Symbolgravur |
+| Varianten | Go / Go mit Auflagen / Zurück / Ablehnung |
+| Menge | je 3 |
+| Material | PLA |
+
+---
+
+## Stückliste (Kurzfassung)
+
+| Teil | Menge | Datei |
+|------|------:|-------|
+| Phasen-Basistile | 40 | `openscad/aktivitaets-tile.scad` |
+| Aktivitätsplättchen | 37 | `openscad/aktivitaets-plaque.scad` |
+| Action-Stein | 2 | `openscad/action-stein.scad` |
+| Aktiv-Feld (RACI-Leiste) | 1 | `openscad/aktiv-feld.scad` |
+| Gate-Tor | 3 | `openscad/gate-tor.scad` |
+| Rollen-Figuren | ~20 | (Standard-Meeple-Modell + Einfärbung) |
+| Entscheidungs-Chips | 12 | (einfache Münze + Gravur) |
+
+## Hinweise für den Producer
+
+- Toleranzen Sockel/Plättchen an **einem Probedruck** kalibrieren (Drucker-spezifisch).
+- Gravurtiefe 0,6–1,0 mm; bei sehr kleiner Schrift Label-Variante wählen.
+- Farbtrennung über Filamentwechsel je Phase, nicht über Lackierung (abriebfest).

+# OpenSCAD-Modelle
+
+Parametrische Quellmodelle der Schlüsselteile. In [OpenSCAD](https://openscad.org)
+öffnen, Parameter im Customizer anpassen, mit **F6** rendern und über
+*Datei → Export → STL* slicebereit exportieren.
+
+| Datei | Bauteil |
+|-------|---------|
+| `aktivitaets-tile.scad` | Phasen-Basistile (100×100, Verankerung Ø50, Puzzle-Tabs) |
+| `aktivitaets-plaque.scad` | Beidseitiges Aktivitätsplättchen (Ø49) — Text per Variable |
+| `action-stein.scad` | Szenario-Träger mit Kartenschlitz + M8-Gewichtsaussparung |
+| `gate-tor.scad` | Gate-Tor mit 4 Rollen-Steckplätzen + Kartenschlitz |
+
+## Serienfertigung der Plättchen
+
+`aktivitaets-plaque.scad` enthält den Text als Variablen (`front_id`,
+`front_name`, `back_text`). Für alle 38 Aktivitäten empfiehlt sich ein kleines
+Skript, das die Werte aus den `service-lifecycle_*.yaml` liest und je Aktivität
+ein STL erzeugt (z.B. via OpenSCAD-Kommandozeile `-D` Parameter-Override):
+
+```bash
+openscad -o op_05.stl \
+  -D 'front_id="op_05"' \
+  -D 'front_name="Ueberwachen der Services"' \
+  -D 'back_text="..."' \
+  aktivitaets-plaque.scad
+```
+
+## Hinweise
+
+- Gravur-Text bewusst kurz halten; lange Kurzbeschreibungen ggf. auf Label auslagern.
+- Umlaute in Gravuren je nach Font kritisch — im Zweifel `ae/oe/ue` verwenden (so in den Vorlagen).
+- Vor Serienstart **ein** Tile + Plättchen + Stein als Passungs-Funktionsmuster drucken.

+# Visual-Prompts für den 3D-Druck-Producer
+
+Diese Prompts erzeugen **Orientierungs-Renderings** (kein Marketing-Bild),
+die dem Producer Form, Proportion und Steckmechanik der Bauteile zeigen.
+Empfohlen für Bildmodelle wie Nano Banana / Imagen. Englisch erzielt meist die
+sauberste Geometrie; Beschriftungen bewusst sparsam halten.
+
+> **Board-Layout:** linear (durchgehende Bahn), **kein Kreis**.
+> **Wichtig:** die **einseitigen, entnehmbaren Aktivitätsplättchen** müssen
+> sichtbar sein — einige liegen flach in der Verankerung (Code-Seite oben),
+> einige sind herausgenommen und liegen daneben (Rückseite leer), sodass die
+> **freie Verankerung** erkennbar ist (dort steht dann der Action-Stein).

+
+## Prompt A — Bauteil-Übersicht (Exploded-Style)
+
+```
+Clean technical product render, neutral light-grey studio background, exploded
+view of a set of 3D-printed tabletop game components in matte PLA. Show: a square
+modular base tile (100x100mm) with puzzle-tab edges and a round centered recess;
+a round single-sided insert disc that fits the recess (top face with a short
+engraved code, plain back); a cylindrical game token
+with a wide weighted base and a vertical card slot on top; a small upright
+arch-shaped "gate" with peg holes at its base; a meeple figure with a round pin
+foot. Parts floating slightly apart to show how they connect. Soft shadows,
+isometric angle, high detail, dimension-focused, minimal text.
+```
+
+## Prompt B — Aktivitätsplättchen: einseitig & entnehmbar
+
+```
+Close-up technical render of round single-sided game discs in matte colored PLA,
+each about 49mm diameter and 4mm thick with a chamfered edge for easy gripping.
+Three discs shown: one sitting flush inside a square tile's round recess (top face
+showing a short engraved activity code), one lifted out by fingers, and one lying
+beside the tile with a plain blank back. The empty recess of one tile is clearly
+visible (this is where the upright action token will stand). Emphasis on the
+removable fit and the freed socket. Neutral grey background, soft studio light,
+shallow depth of field, premium board-game component photography.
+```
+
+## Prompt C — Action-Stein im Detail
+
+```
+Close-up technical render of a single 3D-printed game token, matte white PLA.
+Cylindrical body on a wide round base, with a vertical slot on top holding an
+upright rectangular card. The base diameter is clearly wider than the body for
+stability. The token stands inside a square tile's round recess (the same recess
+that normally holds an activity disc). Quarter-section cutaway shows a hexagonal
+cavity in the base for a metal weight. Neutral grey background, soft studio
+lighting, isometric, emphasis on proportions and the card slot fit, no decorative
+text.
+```
+
+## Prompt D — Gate-Tor mit Rollen-Steckplätzen
+
+```
+Technical product render of a small upright arch-shaped game piece in matte PLA,
+like a doorway about 100mm tall with 90mm clear opening, 8mm thick. Two flat feet
+at the base spanning two tiles of a straight track. A row of four small round holes
+along the front base edge for inserting pin-footed figures. A thin horizontal slot
+across the top of the arch holding a small reference card. A round-pin meeple figure
+is inserted in one of the base holes. Neutral background, isometric, soft shadows,
+focus on the peg-hole mechanism, minimal text.
+```
+
+## Prompt E — Tile-Steckmechanik (gerade Bahn)
+
+```
+Top-down and slight-angle technical render of four square modular game tiles
+(matte PLA, different solid colors: blue, orange, green, teal) connected via
+puzzle-tab edges into a STRAIGHT row / track. Each tile has a round recessed socket
+in its center: two sockets hold flat round single-sided discs (engraved code on
+top), one socket is empty showing the recess, one holds a small upright arch gate. Clean grey background, soft light, isometric, emphasis on how
+tiles interlock into a straight line, minimal text.
+```
+
+## Prompt F — Komplettaufbau (Referenz für Proportionen)
+
+```
+Wide isometric technical render of a fully assembled LINEAR tabletop game on a
+neutral surface: square color-coded tiles connected into a long straight track
+left to right through five color zones (blue, orange, green, teal, purple); two of
+the zones (green and teal) sit side by side with two curved arrows forming a small
+loop between them; three upright arch gates stand on the track; small meeple figures
+placed at the gates; round single-sided activity discs sit in the tile sockets with
+a couple lifted out leaving empty sockets; one cylindrical token with an
+upright card stands in a socket; at the right end two exit arrows lead off the board.
+Matte PLA materials, soft studio lighting, clean and diagrammatic,
+proportion-accurate, minimal text.
+```
+
+## Prompt G — Gesamtaufbau, 40 Einzeltiles (Tisch-Optik)
+
+> Hinweis: Bild-KIs zählen nicht zuverlässig — die exakte Tile-Zahl ist über
+> [`board-layout.svg`](board-layout.svg) garantiert. Dieser Prompt liefert die
+> **Optik/Stimmung**, nicht die exakte Anzahl. Raster explizit vorgeben erhöht
+> die Trefferquote.
+
+```
+Isometric high-angle photograph of a complete modular tabletop board on a large
+wooden meeting table, spanning about 1.2 meters. The board is assembled from many
+small individual square puzzle tiles interlocking via tab-and-slot edges; each tile
+is one lifecycle step. Tiles are color-grouped into five phases laid out as fixed
+grids: DESIGN (blue) 4 tiles, TRANSITION (orange) 12 tiles with three of them marked
+by a small upright arch gate, OPERATION (green) 7 tiles, SUPPORT (teal) 11 tiles,
+REVIEW (purple) 6 tiles. Each tile has a round recessed socket holding a flat
+single-sided disc; a few discs are lifted out leaving empty sockets. Between the green and teal phases two curved arrows form a
+small loop; two exit arrows leave the purple phase at the right. A cylindrical token
+with an upright card stands in a socket at the start. A coffee mug and notebook give
+scale. Soft daylight, matte PLA surfaces, clean modern design, large phase labels
+only, minimal small text.
