Use clean corrugated cardboard to make a removable divider grid. Measure the drawer before cutting; rails and handles can reduce the usable space.
Design the compartments
List the items you want to store and sketch the divider positions. Start with a few wide compartments. You can add cross pieces after testing the fit.
Test the slots
Cut two scrap strips and join them with crossing slots. The fit should hold the grid upright without forcing the cardboard to buckle. Adjust the slot width before cutting the rest of the dividers.
Cover the edges
Paper tape, paper or fabric can cover exposed corrugation. Keep covering thin at the slots so the grid still fits together. Let adhesive set before placing the divider in the drawer.
This project is a general plan. Materials, dimensions and construction details may need adjustment for your tools and supplies.
