I've noticed all 3D AI generators create monlithic blobs that are impossible to edit. So, alongwith a friend, I built this project where you can generate 3D objects with separate, editable parts.I'm looking for community feedback. The tool is free, but you'll have to BYOK. It uses models like Gemini, Claude or chatGPT to generate a Blender construction script. Basically the output is not merely geometry. It's the procedure that built it, plus the asset itself. This means you can actually go in and edit the "kit of parts" afterwards, instead of starting over.

Could you build this?
Partial While prompting an LLM like Gemini to generate segmented code (such as OpenSCAD, Three.js, or CSG primitives) and rendering them in a web viewer is achievable, generating truly arbitrary, functional, multi-part 3D CAD/mesh assets reliably requires complex parametric modeling engines or custom 3D representation models.
What it would actually take: A production implementation requires a structured scene graph and CAD-kernel abstraction (such as OpenCASCADE via WebAssembly or Three.js CSG). The backend orchestrates multi-step LLM planning to break down the target model into modular components with relational bounding boxes, mating constraints, and individual mesh/code generation. The key difficulty is ensuring geometric coherence, watertight topology, and exact mechanical fits between generated parts without hallucinated interpenetrations.
