The drawer
Measure the inside of the drawer, the clear space the grid has to fill, not the outside of the drawer.
The grid
A little clearance lets the pieces slide together without forcing. 0.3 mm suits most printers.

A drawer full of loose things is a drawer you dig through. A grid of dividers turns it into places, so the thing you want has a spot and stays in it. This prints a set sized to your drawer, in pieces that slot together with no glue.
How it goes together
The pieces egg-crate. The long dividers have notches cut in the top, the cross dividers have notches in the bottom, and they drop together halfway so the whole grid locks square and stands up on its own. It sits in the drawer and uses the drawer walls as the outside of the grid, so you print only the inside dividers, which saves plastic.
What each setting does
Inside width, depth and height. Measure the clear space inside the drawer, not the outside. The grid is sized to fill it, so the pieces reach the walls. Height is how tall you want the dividers; 25 to 40 mm stands well without being in the way.
Columns and rows. How many compartments across and deep. The compartment size shows as you change them, so you can dial it to what you are storing.
Wall thickness and slot clearance. Thin walls save plastic and print fast; 2.5 mm is strong enough for a drawer. The clearance is the little bit of room in the slots so the pieces slide together without forcing. 0.3 mm suits most printers; add a touch if yours runs tight.
Printing it
The whole set comes in one STL, laid out flat on the plate. Print standing as it comes, flat, with 3 or 4 walls and about 15 percent infill, no supports. PLA is fine. If the longest strip is wider than your bed, print the long ones in two halves and butt them, or split the drawer into two grids.
Before you download
The file is read back before the button turns on: every edge of every piece shared by exactly two triangles, every face pointing outward, a positive volume. If the grid cannot be made, such as compartments too thin to stand, the page says why instead of handing you a broken file.
