ThermoBoo - Ghosts You Shape Yourself

👻 ThermoBoo - Ghosts You Shape Yourself

A ghost that folds itself to life.
ThermoBoo is a playful experiment in material, motion, and making — a flat PLA sheet that naturally folds into a ghost when you pour hot water on it.

No pre-posed geometry or rigid surfaces — the shape forms through heat, gravity, and your hands.

Once poured, the thin sheet softens and drapes smoothly around a small forming core, creating soft, fabric-like folds with almost no visible layer lines.

The result feels oddly alive: smooth, soft folds that behave like real fabric, formed from a thin, flat sheet.
Each ghost shapes differently, each face reacts uniquely, and every maker leaves their own small fingerprint of craftsmanship.
 

Choose your ghost from six classic personalities — Edmund, Friedrich, Jonas, Agnes, Ernest, and Hilda — and watch it come alive in your hands. Minimal print, maximal effect — a single sheet of PLA becomes a personal craft.
 

And when placed on a surface, its hollow underside perfectly fits a small LED candle, turning the ghost into a glowing little spirit for your desk or window.

 

📦 Parts List

• Core base (for snapping and shaping)
• Flat PLA sheet (choose your ghost’s expression)
• Optional stand base (for floating or glowing display)

🖨️ Print Instructions

• Printed in PLA, except for the core, which is recommended in PETG.
• PETG withstands repeated hot water exposure; PLA works fine but may deform after multiple uses.
• No supports required for any part.
• Layer height: 0.28 mm
• Core:
  • Material: PETG (preferred) or PLA
  • Walls: 3
  • Infill: 6% (PETG) or 15% (PLA)
• Ghosts:
  • Material: PLA
  • No special settings needed

💧 Forming Instructions

1. Snap the flat sheet pin to the core.
2. Place it in a sink or large flat container.
3. Pour about 300 ml of hot water (~80 °C) evenly over the sheet. Start from the back and move towards the center of the sheet.
4. Watch as it softens and folds itself by gravity, wrapping naturally around the core.
5. While still warm, you have a short moment to adjust or tighten folds — each tweak changes its posture and flow.
6. Remove the core once the shape holds.
7. To let it stand, re-dip the bottom edge in hot water and gently press on a flat surface to form a base.
8. Or, place it levitating on the stand for a lighter, floating effect.

🔄 Adjusting & Refining

After the initial forming, you can refine the shape using one of three methods:

1. Pouring fix: While the ghost is still on the core, pour another wave of hot water to slightly re-soften and fine-tune the folds.
2. Quick dip: Remove the ghost, dip it gently into a jar or can of hot water for a few seconds, and shape by hand.
3. Full reset: For starting over, place the ghost in a wide shallow container, pour enough hot water to fully soften it, then straighten the sheet and lay it flat on a table or countertop to cool. Once reset, it’s ready to fold again.

⚠️ Safety Note

Hot water can cause burns.
Always handle with care, use heat-resistant gloves or tools if needed, and avoid direct contact with freshly boiled water.
Work on a safe surface (sink, tray, or container) and let the parts cool before touching or reshaping.
