Drawerforge

What is Drawerforge?

Drawerforge is a pair of free browser tools for Gridfinity, made by Oliver Johnson. You start with the inside width and depth of your drawer in millimeters or inches. The Baseplates page works out the grid, turns the leftover space into margins, half cells or a gap, and splits the plate for your printer in Balanced, Staggered, Fewest plates or Manual mode, where you click grid lines on a cut map. The pieces join with one of seven connectors, such as dovetail tabs, bowtie keys, snap clips or H-clips, and you can add magnet pockets and screw holes in a solid floor or in corner bosses only.

The Bins page carries your drawer size over. You drag bins across a map of the drawer or fill the rest automatically, stack layers of bins on bins with checks that warn when a stack would rock or overhang, and set each wall to full, two thirds, half, a low lip or open, which also makes flat trays and lids. Bins get dividers, stacking lips, magnet and M3 screw holes, and a label shelf with raised text. A see-through drawer shell in the preview shows whether everything fits.

Exports are an STL per part, a 3MF with every part already arranged on print plates, connector keys, a fit test tile, a joint fit sample with four clearances, and a ZIP with a README and assembly order. A print plan estimates material and time. It is free with no account and nothing is uploaded; the code is on GitHub under the AGPL-3.0, and a notice in the repo says the models you make are yours to use and sell.

What you can make
