Need a custom Gridfinity bin without spending time editing a CAD model? I have built a free online Gridfinity bin generator that lets you configure a storage bin in your browser, preview it in 3D and download a ready-to-print STL file.
Open the TekOnline Gridfinity Bin Generator
The tool is designed for practical workshop, electronics bench, tool drawer and parts-storage setups. Choose the footprint and height you need, add optional features, generate the model and download the STL for your slicer.
What is the TekOnline Gridfinity Bin Generator?
The TekOnline Gridfinity Bin Generator is a browser-based tool for creating custom Gridfinity-compatible storage bins for 3D printing. It removes the need to find the closest premade model or manually modify a CAD file every time you need a slightly different organiser bin.
You can use the generator from a desktop browser at http://gridfinity.tekonline.com.au/.
Gridfinity bin generator features
- Custom grid size: set Grid X and Grid Y from 1 to 20 units.
- Adjustable bin height: choose from 1U to 50U, where each height unit is 7 mm.
- Magnet holes: add holes for magnetic Gridfinity setups.
- Screw holes: generate bins with screw-hole support.
- Label lip: add a front label area for easier drawer organisation.
- Front scoop: improve access to small components and fasteners.
- Basket sides: enable or disable the basket-style side layout.
- Internal dividers: add X and Y dividers to split a bin into smaller compartments.
- 3D preview: inspect the generated model before downloading it.
- STL download: export the finished Gridfinity bin for your slicer and 3D printer.
How to generate a custom Gridfinity STL file
- Open the free Gridfinity bin generator.
- Choose your Grid X and Grid Y footprint.
- Set the bin height in Gridfinity height units.
- Select options such as magnet holes, screw holes, a label lip or a front scoop.
- Add dividers if you want multiple compartments inside one bin.
- Click Generate Preview.
- Check the 3D preview, then download the STL file and open it in your slicer.
Useful Gridfinity bin ideas
A custom Gridfinity STL generator is useful when a standard bin is almost right but not quite suitable for the job. Some practical examples include:
- Small divided bins for screws, nuts, washers and electrical connectors
- Taller storage bins for tools, probes, drill bits and workshop consumables
- Labelled electronics-component bins for resistors, capacitors and modules
- Scoop-front bins for frequently used fasteners
- Magnetic bins for portable Gridfinity trays and work surfaces
Gridfinity dimensions used by the tool
The generator uses the familiar Gridfinity layout: each X or Y grid unit is 42 mm, and each height unit is 7 mm. The page updates the overall dimensions as you adjust the controls, which makes it easier to build a bin that fits your drawer, baseplate or project box.
Frequently asked questions
Is the Gridfinity bin generator free?
Yes. The TekOnline Gridfinity Bin Generator is free to use online.
Does the tool download STL files?
Yes. After you generate and preview a custom Gridfinity bin, you can download the STL file and import it into your preferred slicer.
Can I create divided Gridfinity bins?
Yes. The generator supports X and Y dividers, so you can create multiple compartments inside one bin.
Can I add Gridfinity magnet holes and screw holes?
Yes. Magnet holes and screw holes can be enabled independently when configuring a bin.
What size Gridfinity bins can I make?
The current generator supports footprints from 1×1 to 20×20 grid units and heights from 1U to 50U.
