How to Turn Photos Into Free 3D Action-Figure Models With Google Gemini: Step-by-Step Guide

Google has rolled out a fun and innovative feature called Nano Banana, powered by Gemini 2.25 Flash Image technology, which lets users convert ordinary photos into detailed 3D collectible figurines. The best part? You don’t need any expensive software or advanced design skills—just a Google account and a browser.

Here’s a quick guide to creating your own action-figure style 3D models for free.

Step 1: Open Google AI Studio

Visit Google AI Studio on your browser, click on Try Gemini, and sign in with your Google account. If you don’t have one, setting it up takes only a few seconds.

Step 2: Select Nano Banana

Start by picking Nano Banana (Gemini 2.25 Flash Image) from the right-side menu. Accept the terms and conditions, and you are ready to go ahead with it.

Step 3. Upload the Photo

Click the + icon near Run and upload the image you want transformed. It could be a selfie, a picture of a pet, or one of a scenic landscape-anything goes.

Step 4: Run the Prompt

Paste the following prompt in the chatbox and hit Run:

“Create a highly detailed 1/6 scale figurine of the character(s) from the uploaded photo in a semi-realistic style… [rest of collectible figurine display description].”

This prompt generates a lifelike, showcase-ready figurine inside a virtual glass display case.

Step 5: Save and Share

Once the AI generates your figurine, simply download the file and share it on Instagram, X, or with your friends.

Pro Tips for Better Results

• Use high-resolution photos for sharper models.
• Use custom prompts that emphasize the strengths of your figurines.
• Start with simpler images and move your way to the complex.

Since Google came out with Nano Banana, all you have to do is shoot everyday photos and then make the AI work to churn out these professional-grade 3D collectibles—a neat alternate way of working for creativity and AI.
