About This Site

Last updated: May 19, 2026

3D Shape Viewer & STL Exporter is a free, browser-based tool for exploring and creating 3D geometry. It is built with modern web technology so it runs instantly in your browser — there is nothing to install, and no account is required.

What the Tool Does

Interactive 3D viewing — rotate, zoom, and inspect 3D shapes in real time with smooth, hardware-accelerated rendering.
Real-time parametric editing — adjust the dimensions and parameters of each shape and see the geometry update immediately as you work.
Water-tight STL export — export your shapes as clean, water-tight STL files ready for 3D printing, slicing software, or CAD workflows.

All processing happens locally in your browser. Your models are generated and exported on your own device, and nothing you create is uploaded to a server.

Who Operates This Site

The Site is created and maintained by [YOUR NAME OR COMPANY]. It is an independent project focused on making 3D modeling and STL export simple and accessible to everyone.

Our Mission

Our mission is to provide a fast, friendly, and genuinely useful 3D tool for makers, students, hobbyists, educators, and designers — lowering the barrier to creating print-ready 3D geometry without expensive software or a steep learning curve.

Free and Ad-Supported

This Site is completely free to use. To keep it free and to cover hosting and development costs, the Site is supported by advertising. We appreciate your support in allowing ads, which makes the tool available to everyone at no charge.
