OpenSCAD 42 mm Grid Organizer example
Practical parts
Lesson 19 of 22
Lay out useful compartments on a fixed pitch while keeping walls, floor, and outside clearance independent.

Visual walkthrough: change step in the workspace Parameters panel to compile each construction stage.
How this model works
The outside envelope is cell count times 42 mm, minus a single overall clearance allowance. Divider centerlines stay on the nominal pitch rather than being redistributed across the smaller envelope. The cavity starts above the bottom to retain a floor. Dividers overlap the shell and floor slightly, making one connected part. This flat-bottom tray has no mating feet, stacking lip, magnets, or standardized interface; a 42 mm pitch alone does not establish Gridfinity compatibility.

Make it your own
Make a three-by-one organizer. Use the shell step to inspect its floor, then add compartments and measure the 42 mm divider pitch. Adjust the outside clearance for a measured drawer, not an assumed standard fit.
Change one parameter at a time and inspect the result. Use the workspace reset action to return to this lesson’s original model.
