The author runs Qwen 27B (Quasar QAT, 590k nvfp4 context, image processing enabled) on a 5090, and Qwen-Image 2.1 (int8) via ComfyUI on a 3080 10GB, with the Pi agent harness building its own skills for CadQuery, Blender, and ComfyUI.

A single prompt asked for printable 3D models of a self-watering plant pot and a MagSafe phone stand, multi-view render sheets, and an ad-style composited scene. Output isn't perfect but impressive — the view sheet even lists filament usage per object. Next goal: feed photos of a real object and get a faithful 3D model for custom RC car parts.
