DRAWERFORGE

Gridfinity baseplates cut to your drawer — measured, split for your printer, joined, and ready to print. Start with the space you have; everything else follows.

Measure the drawer in
Internal dimensions. Measure at the tightest point and subtract 1–2 mm (about 1/16 in) so the assembly slides in.

Not listed? Pick the size nearest below your bed, or Custom and type it in. Beds are always in millimetres — every maker quotes them that way.
Only affects the material estimate, not the geometry.
With a price set, a cost goes beside every gram figure; leave it empty and none is shown.

Staggered offsets joints between rows like brickwork so seams never line up.

Tabs on one piece drop into open-bottomed pockets on its neighbour. Assemble on a flat surface, then lower the whole plate into the drawer. Placed at every wall junction along each seam.
0.2 suits most printers. Print the test tile pair first; tighten to 0.15 or loosen to 0.25 from there.

A solid floor puts at least 2.8 mm of plastic under the whole plate, and more when a magnet or screw head is deeper than 2.6 mm, so a pocket always keeps a layer under it.

Defaults follow the Gridfinity spec (42 mm pitch, three-part profile, 4.25 mm plate). Change pitch only for non-standard bins.

Nothing is generated until you ask for it. The dialog lists every file you get, and says whether it all fits your bed. The link carries your whole design — it is the thing to attach to a bug report.

Two formats: a 3MF is a whole print plate with every part already arranged on the bed, so it opens in your slicer ready to slice; an STL is one part on its own, for when you would rather arrange them yourself.
STLs are millimetre-scale and print flat as oriented, no supports. Print the test tile first and check a bin seats in it before committing to the full plates.

Your drawers

Each saved drawer keeps its baseplate and its bins together, on this device only. The one that is open saves itself as you work, and opening another brings back both halves of it, on either page.

A design file is a small JSON file of settings — no 3D models, which are rebuilt from the settings. Use one to move drawers to another device, to keep a backup, or to attach to a bug report.
