What magnets fit the magnet holes?
The base pockets are sized for the de-facto Gridfinity standard: Ø6 mm × 2 mm neodymium disc magnets, one per 42 mm base corner. Glue-in is optional — bins also sit fine on a baseplate without magnets.
Gridfinity bin generator: custom bins, real CAD underneath
Size a Gridfinity bin in 42 mm grid units, add dividers, magnet holes and a scoop, and watch the model rebuild in your browser. Unlike one-shot STL customizers, every bin is parametric CAD code — so when you need something the sliders don't cover, the AI agent edits the same model for you.
- - True Gridfinity spec: 42 mm pitch, 7 mm height units, stackable lip
- - Dividers, magnet holes (Ø6 × 2 mm) and scoop as simple toggles
- - Exports clean STL / STEP / 3MF — printable without supports
- - Need a label shelf or a custom cutout? Remix it with the AI agent
Parameters you can tune
Each parameter below rebuilds real geometry on every change — this is parametric CAD, not a scaled mesh.
| Parameter | Default | Range | What it does |
|---|---|---|---|
| Grid units X | 3 u | 1 – 8 | Bin width in 42 mm Gridfinity units. |
| Grid units Y | 2 u | 1 – 8 | Bin depth in 42 mm Gridfinity units. |
| Height units | 6 u | 2 – 12 | Bin height in standard 7 mm increments. |
| Compartments X | 1 | 1 – 6 | Number of compartments along the width. |
| Compartments Y | 1 | 1 – 6 | Number of compartments along the depth. |
| Stacking lip | True | on / off | Top lip so another bin stacks on this one. |
| Magnet holes | False | on / off | Ø6 × 2 mm magnet pockets in every base corner. |
| Scoop | True | on / off | Curved front floor so small parts slide out. |
How it works
- 1.Open the generator — the model builds right in your browser, nothing to install.
- 2.Tune dimensions and options in the parameter panel; the geometry rebuilds live in 3D.
- 3.Export STL / STEP / 3MF for printing — or ask the AI agent for features beyond the sliders.
FAQ
Do Gridfinity bins print without supports?
Yes. The base profile, stacking lip and scoop are all designed within FDM overhang limits. Print bins flat on the bed in PLA or PETG at 0.2 mm layers; no supports and no brim needed on a clean bed.
Can I change something the parameters don't cover?
Yes — that is the point of Forgent3D. The bin is generated from editable CAD code, so you can open it in the workbench and ask the AI agent for label tabs, finger slots, custom cutouts or a non-standard footprint.
