TraceBin: Gridfinity Bins

Lay a tool on a sheet of paper, take one photo, and TraceBin builds a Gridfinity bin with a pocket shaped like your tool. Adjust clearance and height, add a finger notch, inspect the 3D preview, and share an STL with your slicer. Processing happens on your iPhone, with no account or upload.

• Works with US Letter or A4 paper as the scale reference. No calibration card or marker sheet.
• Adjustable clearance and bin height, with pocket-depth options.
• Add one circular finger notch per Gridfinity bin. Position it in a full-screen editor with zoom and fine-position controls.
• Flat insert mode makes a shadow-board insert for your drawer. Finger notches are available for Gridfinity bins only.
• Export binary STL for your slicer.
• History keeps exported bins so you can share them again. Save notch edits to existing bins with Done.
• Use the built-in test coupon to check clearance for your printer.

One tool per photo. Gridfinity bins use a 42 mm grid and 7 mm height units.
