Gridfinity Studio

中文

A browser-only parametric generator for standard 42 mm Gridfinity risers and trays. It previews the final solid interactively and exports binary STL or a Bambu Studio project 3MF.

Open Gridfinity Studio — no installation required. Model parameters, geometry generation, and exports all stay in your browser.

Features

• Risers with printer-constrained X × Y grids, integer heights from 1U, and either a rounded stacking receiver or a fully smooth top.
• Standard trays from 2U, with a rounded stackable rim or a flush nominal-height rim.
• A 2D divider editor that merges and splits 42 mm minimum cells, plus quick whole-cell equal divisions.
• Build-volume limits derived from 14 official Bambu 0.4 mm printer profiles.
• Shadow-free MatCap preview with unrestricted orbit, pan, zoom, fit, and reset controls.
• Binary STL and Bambu project 3MF export; parameter JSON export is intentionally not included.
• Bambu projects include machine, 0.20 mm Standard process, Bambu PLA Basic filament, Gridfinity print overrides, and print orientation.
• Automatic Chinese/English locale detection with a persistent manual selector.
• Local processing: parameters, geometry, and exported models are not uploaded.

Preview and both export formats use the same boolean-unioned, watertight solid. The UI's “single solid” result is a connectivity check, not a visual overlap of separate shells.

Gridfinity conventions

• 42 mm planar pitch.
• 42N - 0.5 mm outer envelope for N cells.
• 1U = 7 mm height unit.
• Risers start at 1U; U is their effective lift after seating.
• Trays start at 2U; U × 7 mm is nominal total height including the universal bottom profile.
• The universal feet seat inside a baseplate or lower receiver, so they do not add effective stacked height.
• The stackable rim extends about 3.55 mm above the nominal U plane and is not straight-wall storage depth.
• Usable tray depth is U × 7 - 4.75 mm bottom profile - floor thickness.

See the 42 mm compatibility notes for the complete geometry and magnet-hole policy. This project omits magnet holes by default; magnets and screws are optional retention methods, not required positioning geometry.

Development

Node.js 22 or newer is recommended.

cd web
npm ci
npm run dev

Vite listens on http://127.0.0.1:4173/ by default. Run all Web checks with:

cd web
npm test
npm run build

Generated exports/, Web dist/, dependencies, and slicer scratch output are not versioned. The JavaScript/TypeScript Web generator is the only authoritative implementation.

Printing

• Bambu project 3MF exports auto-flip smooth-top risers so the smooth face sits on the build plate.
• Other risers and trays print with standard feet down. The Gridfinity bottom profile is designed for printable overhangs and normally needs no supports.
• The included starting preset uses 3 walls, 15% gyroid, no supports, and no brim. Always review slicing for the actual material, size, and printer.
• Print a 1×1 interface sample before a large batch and verify fit against the actual baseplate and drawer.

Browser geometry checks and community-model comparisons do not replace a physical fit test.
