Made right here: a pocket for every tool, cut into a solid block or hollowed to thin walls, with finger holes, names, a stacking lip and magnet or screw holes. STL or 3MF. Every other bin is on VERTEX, our free 3D printing generators.
VERTEX Gridfinity ↗Sheet 1 of 1 · photo to part
Measured
from one
photo.
Tracer uses the sheet of paper under your tools as its ruler. Every outline comes back measured, then lay them out and make a Gridfinity bin with a pocket for each tool, a flat tray, or cut lines for foam and a laser.

Sheet 2 · the method in three views
-
01 · Lay flat
Tools on a sheet of paper
A4, Letter, A5 or A3, on a darker surface so its edges stand out. Keep tools off the paper's edge.
-
02 · Shoot from above
One photo, straight down
All four corners of the paper in the frame, in even light. The straighter you shoot, the closer it measures.
-
03 · Make it
A bin, a tray or cut lines
Lay the pockets out, add finger holes and names, and download STL or 3MF to print, or DXF and SVG to cut.

The photo, and the paper it found
If the green frame isn't on the paper's corners, drag each corner onto it and trace again.
Sheet 3 · make it
A bin, a tray or a foam insert
Lay the pockets out: drag one to move it, turn it with its round handle, and press Reshape to pull its edge where it should be. Add finger notches and shapes from the rail. Tools from earlier photos are under Add from the library.

Lay the pockets out, then make it.
Your traced tools are kept in this browser, so a bin can hold tools from several photos.
Method
The paper is the ruler.
A photo has no scale on its own. A sheet of paper does: its size is known to the millimetre. Tracer finds the sheet, straightens it, and measures everything on it against it.
- 01Find the paper
Two ways of finding the sheet's four corners run on the photo, and the one whose straightened sheet looks most like plain paper wins. If neither finds it, you drag the corners on yourself.
- 02Straighten it
The four corners are mapped onto a perfect rectangle of the paper's size, four pixels to the millimetre. A photo taken at a slight angle is squared up; one taken at a steep angle still loses some accuracy, because the tools have height and the paper doesn't.
- 03Find each tool
The light is evened out across the sheet, then each tool is found by its colour against the paper and by the crisp line round its edge. Soft shadows are peeled off, so a shadow doesn't make a tool look bigger. Specks of dust and creases are ignored.
- 04Draw it
Each outline is fitted to the tool's edge, smoothed a little, grown by your clearance, and measured. What you download is in millimetres at true size.
A photo that measures well
- Shoot straight down from about arm's length, with the whole sheet filling most of the photo.
- Put the paper on something darker than it, so its edges are clear.
- Use soft, even light: daylight from a window, or two lamps either side. One hard light casts a shadow that can join two tools together.
- Keep tools a finger's width apart and off the paper's edge.
- Thick tools measure largest at their widest point, seen from above. If a tool has a high handle, check its size with calipers.
Tracer straightens the paper in your browser, then asks our AI (on our own server) to find each tool on the sheet, and fits every outline to your photo's edges. Nothing is kept. With the AI switched off, or busy, the whole trace runs in your browser and nothing is sent anywhere.
Outputs
One trace, made into anything.
Choose Foam or laser cut lines: the insert's edge, every pocket with its finger hole joined on, and the names, as DXF and SVG. Cut it on a laser or a drag knife, or print it full size and cut by hand.
Print a flat tray with the tools sunk in, or engrave the cut lines on ply or acrylic so every tool has its place. Check the file in the Lasercut vector checker first.
