Description
🌡️ A Flame That Burns Cool
This simple flame stake changes colour with temperature — designed especially for thermochromic filament that shifts around 31 °C (blue → white).
When your plant pot or windowsill warms up through sunlight, the flame fades from blue to white, giving you a calm, visual cue that things are heating up.
☀️ Why It’s Useful
Most indoor plants start to experience root stress above 30 °C.
On sunny window ledges or in conservatories, soil and pots can easily exceed that — even when the room still feels comfortable.
When your Thermo Flame turns white, it’s telling you:
“Time to move me out of the sun or give me a drink.”
As the pot cools again, the blue hue returns — endlessly reversible and fun to watch.
🔥 Design Highlights
- Vertical flame with a graded heat response — thin outer edges change faster, thick core fades slowly for a natural glowing effect.
- 75 mm hexagonal stake grips soil securely and prints neatly.
- One-piece design — no supports required.
- Works with any thermochromic PLA (31 °C type recommended).
- Fast, lightweight print (≈ 20 g filament).
