Magnet-free Gridfinity, generated in the browser. Baseplates that fill any drawer, bins in any size, and pockets cut to the shape of a real tool — photograph it next to a ruler and the outline comes off the picture. Everything exports as STL or STEP.
No magnet bores, no screw counterbores, nothing to glue in. The plate holds bins by the 45° wedge of the standard profile alone, which is what stops them sliding in a drawer. Plates print upside-down-free: flat on the bed, no supports.
Plain background, no shadow under the tool, and hold the camera square-on from directly above — the scale comes from one distance on a flat plane, so a tilted photo stretches one end of the tool relative to the other. Lay the ruler flat beside the tool, not on top of it, and keep both near the middle of the frame where lens distortion is smallest.
A dark tool on white paper, or a light one on a dark bench, traces best. If the trace comes out wrong it is usually faster to drag the line into place than to keep fiddling with the sliders.
A generator for the Gridfinity storage system — a 42 mm grid, invented by Zack Freedman, that lets bins from anywhere sit in a tray from anywhere. You give it a drawer and it gives you the plate; you give it a photograph of a tool and it gives you a bin with that tool’s shape cut into it.
Magnet-free means exactly that: no magnet bores, no screw counterbores, nothing to glue in, nothing to order. Bins are held by the 45° wedge of the standard profile alone — which is what actually stops them sliding when a drawer is shut.
Baseplate — type in your drawer, get the tray. Leftover space becomes a solid skirt so the plate fills the drawer rather than rattling in it, and anything too big for your printer is split into tiles that cut on grid lines and go back together exactly.
Bin — any footprint, any height, with or without a stacking lip, hollow or divided into compartments.
Tool scan — photograph the tool from straight above with a ruler beside it, drag along a known distance to set the scale, and the outline is traced for you. Where the trace is wrong, drag the orange line and it bends. Then it becomes a pocket.
Standard Gridfinity, magnet-free. Everything is generated from these numbers:
| Grid pitch | 42.00 mm |
| Height unit | 7.00 mm |
| Foot / socket profile | 0.80 + 1.80 + 2.15 = 4.75 mm |
| Bin footprint (1×1) | 41.50 mm, r 3.75 |
| Foot bottom | 35.60 mm, r 0.80 |
| Socket clearance | 0.25 mm per side |
A bin’s body is 7 mm × units. The stacking lip sits on top of that, and
the foot of the bin above sinks 4.75 mm back into it — so a stack grows by exactly
7 mm × units per bin, which is the whole point of the number.
Generators disagree about this. If your existing bins came from one that counts the lip inside the 7 mm module, they will be 4.75 mm shorter than these. Switch Height counts to total incl. lip and they will match.
The STEP export is a real solid B-rep, not a mesh wrapper: coplanar triangles are merged back into single planar faces with proper inner and outer loops, so a wall arrives in SOLIDWORKS or Fusion as one face you can select and dimension. Round corners stay faceted — raise Arc quality to fine if you intend to edit them.
Plates and bins print flat on the bed with no supports. Bins are strongest at 3 perimeters and 15 % infill; the plate is fine at 2 perimeters. Nothing here needs magnets, screws or glue.
No upload, no server, no account. The photograph never leaves the browser — it’s the freya way.
The geometry is built here too, by a solid-modelling kernel compiled to WebAssembly and running in this tab. Close it and nothing of yours is anywhere else.
