Egg-crate dividers turn any drawer or box into organized compartments: walls running one way are slotted from the top, walls running the other way from the bottom, and they slide together crosswise into a rigid grid — no glue, no fasteners. Measure the drawer's interior width and depth (the fit clearance shaves a little off so the grid drops in easily), then choose how many compartments each way. Height should sit a few millimeters below the drawer's rim so it doesn't snag when closing. Print tip: the strips print lying flat — strongest orientation and zero warp, even for long walls. If the slots feel tight when assembling, bump slot clearance to 0.3mm; a firm fit is right, a forced fit will split a wall.
