Steil 3D Configurator adds a Gutenberg block that shows an interactive 3D product. Visitors can rotate the model, pick a colour per part and a finish, and send a quote request with their configuration (including a screenshot of what they built).

Everything is editable from the WordPress admin:

Configurator products — a Custom Post Type. Upload a glTF/GLB or FBX model, let the editor detect its parts, and assign a colour palette, finishes and defaults to each. Reuse the same product across many pages.
The block — pick a product, set the height, choose where the controls sit, and toggle the finish selector, reset button and quote form.

Built on Three.js. Works with classic and block (FSE) themes; styles are scoped so they don’t clash with your theme. No external services or CDNs — everything is bundled locally.

A sample “Lounge chair” product is created on activation so you can try the block immediately.
