Use these parts, along with some 2 inch x 1/8th inch aluminum, to make a customized drawer divider.

Print the parts you need at 0.2 mm layers, 1 extra shell, and 25% infill.

Cut some bars of 2 inch wide x 1/8th inch thick aluminum. The length of each section will depend on what you want to accomplish. File or sand the cut edges to remove any sharp spots of burrs.

Assemble the thing, in the configuration you want. A block of wood and some "forceful persuasion" might help get it all together.
