About this generator
Extrabold Gridfinity Baseplate Generator is a free browser tool that makes Gridfinity baseplates sized to a real drawer and split to fit a real printer. You can enter the space in millimeters or grid units, pick a drawer preset such as the IKEA Alex, or trace a custom polygon for awkward spaces, and the grid preview updates live.
Four plate styles are offered: a normal solid plate, a tray with a closed floor for tiny parts, a skeleton plate that saves filament, and a clip-based plate that needs no magnets. If the plate is bigger than your bed, the generator splits it into printable sections using the strategy you choose and adds connector clips for the seams. Magnet holes, countersunk screw holes, fit tolerance and edge treatments are all adjustable, and the result downloads as STL or 3MF.
It is free, supported by donations, and the models are released under CC0. Anyone filling large drawers on a small printer will appreciate the automatic splitting.
