The fastest way to a custom Gridfinity bin.

A modular workshop-organisation system by Zack Freedman. 42 mm grid baseplates with bins on top. Gridmate produces bins compatible with the public Gridfinity spec (MIT-licensed).

Most tools are weirdly shaped. Calipers can measure a screwdriver in 30 seconds; a multimeter in 10 minutes. A photo captures the silhouette in one shot, and the bin is auto-clearance-padded.

Sub-0.5 mm on a sharp A4 photo. We rectify the paper to the standard 210 × 297 mm and back-solve the px-to-mm ratio. Failure modes (glare, glove, fold) are flagged before generation. A trace takes about eight seconds on an ordinary laptop.

Both. The $6 unlock exports a watertight STL and a 3MF of the same custom Gridfinity-compatible bin, straight from your browser. STL drops into any slicer; the 3MF carries colours and per-object settings for Bambu Studio, PrusaSlicer and OrcaSlicer. No file leaves your device until you export.

Yes, that is the whole point. Anything that can print Gridfinity baseplates handles a Gridmate bin: Bambu, Prusa, Voron, Ender. 0.4 mm nozzle, 0.20 layer height, PETG or PLA. Per-bin print-time and filament estimates live in the Print info panel on the generation screen.

Lay the whole set on one A4 sheet and Gridmate traces each silhouette, then arranges them into a custom Gridfinity-compatible tool organizer: one bin or a tray of pockets. Sockets, wrenches, pliers, bits, gauges: if it casts a clean shadow on the paper, it gets a snug pocket.

Generic Gridfinity bins and dividers give you rectangular compartments sized by grid units; a Gridmate bin has a pocket shaped to the actual tool, traced from your photo. The result still sits on the standard 42 mm Gridfinity grid and prints on the same baseplates, but the tool drops into its own silhouette instead of rattling around a box. Shadow foam does something similar, except it is a cut-once consumable. A Gridmate bin is reprintable and modular.

Online Gridfinity generators build regular bins sized in grid units, and they don't shape a pocket to your specific tool. Measuring with calipers and modelling it in Fusion, Tinkercad or OpenSCAD does get you a custom pocket, but it's minutes to hours of work and needs CAD skill. Gridmate goes from one photo to a tool-shaped, Gridfinity-compatible bin in about eight seconds, no CAD required.

No. The trace runs entirely in your browser, so by default your photo never leaves your device. If you save a bin to your account, we keep a privacy-scrubbed copy of the prepared sheet (EXIF and GPS stripped) so you can re-open and edit it later. Sharing a failed trace with us is strictly opt-in.

Yes. $6 unlocks STL + 3MF export and every Pro feature, on every bin you ever make, with no subscription and nothing recurring. We sell through Polar as merchant of record, so VAT is handled at checkout for EU residents, reverse-charge for B2B with a valid VAT ID, and there's a 14-day refund policy.
