GoKawiilCNET writer builds a 3D-printing app with Google's Gemini 3 Pro in under a day
A CNET reporter tested Google's newly released Gemini 3 Pro model by asking it to build an application for designing 3D-printable objects. Within about 18 hours of conversation-based iteration, the AI produced a working app that let him generate and refine cosplay armor pieces like greaves, pauldrons and vambraces, which he then printed himself.
GoKawiil's interpretation of the reporting above, not reported fact.
The experiment suggests large language models are becoming capable of handling more complex, multi-step software creation tasks quickly, potentially letting non-developers prototype custom tools for niche hobbies. The writer frames the AI's role as handling 'grunt work' while he retains creative control, which could point to a growing pattern of AI-human collaboration in maker communities rather than full automation.
- Google's Gemini 3 Pro model was used to build a custom 3D-printing design app from scratch.
- The process took about 18 hours from initial prompt to a finished 3D-printed object.
- The writer limited the AI's output to tasks he could already do himself, treating it as an assistant rather than a replacement.
