Gridfinity Drawer Insert

Gridfinity works because everything shares one grid, so bins from any source drop into any baseplate. The hard part is the baseplate itself: drawers are rarely a clean multiple of 42 mm, so you end up with a gap that lets the whole grid slide around.

Fits: Any Gridfinity bin or baseplate

Make this one yours. Cadio generates it to your measurements — change the size, slot count, or angle by describing what you need.

What actually matters

Print one single-unit bin first and check it drops into your baseplate without force. If it is tight, your printer is over-extruding slightly — adjust flow rather than scaling the model, or the grid stops being compatible with everyone else's.
Measure your drawer and size the baseplate to whole 42 mm units, then fill the leftover gap with a plain spacer. A stretched baseplate breaks compatibility.
Bins print faster in batches, but leave space between them — a blob on the stacking lip is what stops a bin seating flat.

Questions

Is this compatible with bins I downloaded elsewhere?

Yes, as long as the 42 mm grid and 7 mm height units are kept exactly. That is the entire point of the standard, so do not scale the model to fit a drawer.

How deep should my bins be?

Height units of 7 mm. Six units (42 mm) suits most hand tools and hardware; three units (21 mm) is right for screws and small parts.

Need it in a different size, or with more slots?
