Storybook Host with real 3D models: toon-shaded parts with ink outlines that orbit, open up, explode and work (cells fill up, coils light in turn, gears mesh). Labels follow the parts, and a terms card carries the technical words. Built for STEM students who want to see how something looks and works inside.
What to say
Storybook Host with 3D parts: explain the main components of an electric car and how each one works. Funny first, no product. Queue to nextmaker and send to Telegram.
Storybook Host + 3D parts about how a heat pump works, same format as ev-inside. Show each part opening up.
3D explainer: how a camera lens focuses light, for STEM students, with labels for the technical terms.
How it works
Verify the facts from an engineering source (the narration stays simple, the labels carry the technical words)
Clarity gate on the narration; voice; word timings
Model each part in Three.js (videos/_studio/ev3d.js is the pattern): a pure function of time, so frames can be seeked
One WebGL canvas in a painted card; labels are HTML tags placed on projected 3D anchors
Preview stills, render 60 fps (WebGL runs on the software renderer, about 2 minutes), verify, metadata, queue
At a glance
Best for
How a machine or system works (electric car, heat pump, camera, engine)
STEM study content that must stay entertaining
Any topic where one idea per part can be shown as a moving model
You give
A machine or system and its 4 to 6 main parts
A trustworthy source
You get
1080x1920, 60 fps mp4 plus video-seo.md
Time
About 2 hours the first time for new parts; models are reusable
Cost
Free voice; reader calls about $0.20; no image generation needed for the 3D parts
Good to know
Models are schematic; the description says so
Keep one idea per beat: learner readers fail beats that explain two things

Examples (real results, first 24 seconds)
Inside an Electric CarCar shell fades, battery cells fill in a wave, inverter dots swing back and forth, stator coils light in turn, gears mesh.
