This is a simple 3×1 Gridfinity bin designed for the Opinel №07 folding knife. The bin's height allows for stacking.

Please note that the two photos above are from the initial version. I have since lowered the base level of the bin slightly, making it easier to remove the knife. Both the STL and FCStd files reflect this adjustment, but you can easily modify the height in the FreeCAD source file if desired.

• Filament: PLA works well; other filaments may also be suitable but haven't been tested.
• Layer height: 0.15 mm seems to work well.
• Infill: 5% infill provides ample strength while conserving filament.
• Supports: No supports are necessary.

The FreeCAD source file is available in the Files section. I’m using the Gridfinity FreeCAD plugin for the bin, which allows you to easily add magnet or screw holes by adjusting the parameters within FreeCAD. Please feel free to make any modifications as needed.
