Gridfinity Pic-to-Bin

Photograph a tool lying on a printed marker sheet. Get a 3D-printable gridfinity bin with a pocket cut to the tool's exact shape.

Get it running

1. Install

pipx install gridfinity-pic-to-bin
pic-to-bin-fusion install

The second command adds a Gridfinity Pic-to-Bin button under Solid → Create in Fusion 360 — that's what turns the result into a solid model (enable it with Shift+S →).

No pipx yet? py -m pip install --user pipx; py -m pipx ensurepath (Windows) or brew install pipx && pipx ensurepath (macOS) — then open a new terminal. Needs Python 3.10+. More install options →

2. Print the template

generate-phone-template --paper-size letter

Print the PDF at exactly 100% scale — not fit-to-page. One-time setup; the sheet is reusable.

3. Photograph the tool

Lay it inside the dotted zone, shoot from above with all 8 markers in frame. Measure the tool's depth with calipers — that's the one number the photo can't give you. Photo tips →

4. Start the web app

mkdir ~/pic-to-bin && cd ~/pic-to-bin   # Windows: mkdir $HOME\pic-to-bin; cd $HOME\pic-to-bin
pic-to-bin-web --port 8000

Run it from a dedicated folder — output and the SAM2 model weights (several hundred MB, downloaded on the first trace) land in the current directory.

5. Use it

Open http://localhost:8000, drag in the photo, enter the tool depth, and submit. You get a layout preview, a 1:1 fit-test PDF to print and lay the real tool on to check the fit, and a bin_config.json.

Then in Fusion 360, click Solid → Create → Gridfinity Pic-to-Bin and point it at that bin_config.json. It builds the whole parametric bin — body, pockets, finger slots, stacking lip, gridfinity base pads. Export STL and print.

Prefer the terminal? The web app is a wrapper around one command:

pic-to-bin photo.jpg --tool-height 17
