Floating Memory Tiles — Pool & Beach Sea-Creature Match Game

A classic memory / pairs game (pexeso) built for **summer water play**: 24 chunky tiles (12 sea designs × 2) that **float** — deal them on the beach blanket, or toss the whole set straight into the **pool** and play where they drift.

- **They float by design, not by slicer luck.** Each 40 × 40 × 8 mm tile has a **sealed internal air cavity** (modelled into the geometry, split into cells by internal ribs), so effective density stays below water at ANY infill setting.
- **They hide their own faces in water.** The icon-face skin is deliberately thicker (heavier) than the blank back, so a floating tile **rights itself icon-down**. Flip one to peek; let go and it slowly turns back over. Pool memory plays itself honest — no cheating, no referee.
- **Blank, indistinguishable backs** and rounded chamfered edges — sand-proof, splash-proof, and no cards blowing away in the wind.

**The 12 designs** — starfish, scallop shell, crab, fish, octopus, turtle, anchor, sailboat, sun, lighthouse, palm island, jellyfish. All drawn as plain OpenSCAD 2D primitives (no AI anywhere).

One file: `combined_plate.stl` — a plate of 12 tiles. **Print it TWICE** for the full 24-tile set.

- **Two colours (recommended):** the STL contains two named solids — `plate_body` + `icon_inlays`. Import, then **split to parts** in your slicer (Bambu Studio: right-click → Split to Parts) and assign a contrast filament to the icon inlays. They are flush plugs at the exact engrave coordinates; colour swaps only happen in the top 1 mm, so purge cost is mild.
- **Single colour works too:** just print as-is — the icons read fine as engraved shadows.

**Printing:** no supports anywhere, blank backs against the bed, cavity ceilings are short self-supporting bridges. 0.2 mm layers, any infill. PETG shrugs off sun and pool water; PLA is fine for the season.

**How to play:** shuffle icon-down, take turns flipping two tiles; match keeps the pair, most pairs wins. House rule for the pool: you must flip tiles where they float.
