The exact JSON prompt I use to generate premium 3D icons in 60 seconds with Nano Banana 2.

Thanks for grabbing this — let's get you making icons.

⚡ Quick Start (3 steps)

1. Open Nano Banana 2 on wherever you like (could be Higgsfield, flora, api etc)
2. Copy the prompt below and replace [your thing] with what you want (e.g. coffee shop, bike, mountain cabin)
3. Paste and generate — you'll get a clean isometric icon in ~60 seconds

That's it. No fine-tuning. No Midjourney syntax gymnastics.

🔑 How to replace [your thing]

Just swap it with a simple noun or short phrase. The prompt handles the rest.

Examples that work well:

Tip: Lifestyle / service / product nouns work best. Avoid abstract concepts ("innovation", "trust") — stick to concrete objects or places.
