Gridfinity BuilderParametric CAD for 3D-printable storage

Design bin layouts, inspect mating geometry, and export models for your slicer.

Get Started

Open Application

GitHub

Layout editor

Drag, drop, resize, and rotate bins on a real-time SVG grid with collision detection and snap-to-grid.

Geometry inspection

See your bins rendered in 3D with PBR materials, X-Ray mode, and Blueprint mode — powered by Three.js.

Mating profiles

Fixed foot and socket profiles, dimensional tests, and a printable fit kit. Validate physical fit with your own printer and material.

ZIP, 3MF and STL output

Download a ZIP with a complete 3MF and one STL per part, or choose direct 3MF. Normal exports exclude the preview baseplate; Fit Test includes a small printable baseplate.

Editing tools

Shift+Click multi-selection, Ctrl+C/V/D for copy-paste, Ctrl+A select all, with bulk group and color assignment.

Local workflow

Generate models in the browser, save layouts locally, and use cached application assets offline. Publishing to GitHub Gist is optional.
