What is Binforge?
Binforge is a free browser tool that designs Gridfinity bins, baseplates and trays, built by solo developer Luiz Tanure. It also makes adapters between grid sizes and has a drawer layout planner, and the 3D preview redraws as you move each slider. You can type in the width, depth and height yourself or open one of 33 presets from the gallery, such as a hex bit organizer, a spice jar rack or a dice box.
What sets it apart from simpler Gridfinity generators is the shaping. A bin can have an L, U or ring-shaped footprint, stick out past the grid on one side and hold several cutouts at once, each of which can be rotated or tilted so screwdrivers and pliers sit at an angle. For a cutout that matches a real tool, you photograph it on A4 or Letter paper and click it, and a model running in the browser traces the outline for you to tidy up. Baseplates can follow a custom outline and can be split into pieces that fit your printer bed.
It suits people filling workshop drawers who want more than plain rectangular bins. Before you download, it shows a filament and print time estimate, and a share link keeps the whole design.

Binforge pros
- Goes past plain boxes with custom bin footprints, off-grid extensions and several tilted cutouts per bin
- Photo tracing runs in the browser: shoot a tool on A4 or Letter paper and click it to get a matching cutout
- Exports STL or 3MF, shows filament and print time estimates, and splits large baseplates to fit your bed
Binforge cons
- A small one-person project with little community discussion; stacking, hinged and sliding lids were not available as of September 2026
- With 80+ settings spread over many panels, finding one specific option can take some clicking
- No multicolor or filament-swap output, and the source code is not public
