Design printable Gridfinity parts in your browser and export them as STL. Spec-accurate bins, baseplates, and freeform tool cutouts — fully client-side, no upload, no account.
Gridfinity is an open modular storage system by Zack Freedman, built on a repeating 42 mm grid with 7 mm height units — baseplates tile your drawer and bins drop into the grid. This generator produces spec-conformant parts that interoperate with any other Gridfinity component, generated entirely in the browser with a live 3D preview and one-click STL export. Nothing is uploaded; every design lives in a shareable URL.
Any size in grid units, compartment dividers, adjustable wall thickness, stacking lip, magnet (6.5 × 2.4 mm) and screw (3 mm) holes, finger scoops, and label shelves with adjustable depth.
Light open frames, weighted bases, and magnet / screw-down variants — with hole positions that line up with your bins so they actually couple together.
Drop a reference photo onto the bin surface, trace a freeform outline point by point, and the generator carves it as a fitted pocket — the classic tool / part organiser workflow.
Binary STL export ready for any slicer, shareable parameter URLs, light / dark / auto themes, and an orientation cube so you can read the model from any angle.
