Comb-Slot Movable Divider Bin
A 140 x 92 x 28 mm drop-in parts-bin insert for a tool drawer, tote or case, with a 5.2 mm comb rail down both long walls so the two 86.5 x 23 mm dividers re-key into any of 24 positions — one print covers any mix of screw, nut and connector sizes instead of a fixed compartment layout. Dividers print flat in parking windows in the 2.4 mm floor, and two counterbored pads take M4 screws (4.5 mm clearance bore) to fix the insert down so it stops sliding.
