Baseplates
Any grid up to 12×12. Light skeleton by default, with optional press-fit magnet pockets, M3 screw holes and a lightened floor. Plates bigger than the bed split into tiles with printed-in dovetails.
Fit-to-space mode measures a drawer and adds sprung edges that take up the slack in real wooden drawers.
Open the baseplate builder →Bins
Full or half grid, any height in 7 mm units. Weighted compartments, partial-height dividers, scoops, label shelves and tabs, a rounded floor, and magnets in the feet.
Queue a whole drawer's worth as a print set and get one file with every bin packed onto A1 Mini sheets.
Open the bin builder →Magnetize an STL
Drop in somebody else's baseplate or bin. It is measured against the Gridfinity spec, flipped the right way up if needed, and drilled with the same fit-tested magnet pockets the generator uses.
Floorless "lite" bins get bosses grown round each pocket instead of a hole through.
Open the retrofit tool →How it works
- Set the size. Cells, height, and the options you want. The top-view preview updates as you type.
- Generate. The solid is built by the Manifold kernel in a worker, so the page stays live and the output is always a closed, slicer-clean mesh.
- Print. Open the
_bambu.3mfin Bambu Studio with printer, filament and process settings already set, or slice the STL anywhere. Flat on the bed, no supports.
Built around what actually prints
- Magnets that hold. ⌀6.5 bore with three 0.3 mm crush ribs, print-tested on the A1 Mini in PLA Lite. Press in from below, no glue.
- Magnets that come out again. A slot through the pocket ceiling lets a straightened paperclip pop a magnet free.
- Less filament. Lightened floors cut a magnet plate's material by about 40% with no change to the fit.
- Drawers that aren't square. Measure both ends of each axis and the spacers become wedges, with a sprung wave edge that absorbs ±1.5 mm of bow and seasonal movement.
- True chamfers. Feet and sockets are lofted from the Gridfinity profile, not stacked slabs, so stacked bins seat exactly on a 7 mm pitch.
- Bambu Studio projects that keep your settings. Drop in a project exported from your own Bambu Studio and every build uses its printer and filament profile untouched.
