Gridfinity Bins for Küpper Tool Chest Drawers – 20 mm Height Series, Stacks Fit 120 mm, 24 Bins

What it is

Plain Gridfinity bins sized for Küpper tool chest drawers. These drawers (449 × 446 mm inside) take a 10 × 10 Gridfinity grid and leave 120 mm of headroom under the drawer above, so every bin here has an overall height, stacking lip included, in 20 mm steps from 20 to 120 mm. Pick heights that add up to 120 (20 + 100, 40 + 80, 60 + 60, 3 × 40, 6 × 20…) and the stack always clears the drawer above.

The matching baseplate for the Küpper drawer is here: https://www.printables.com/model/1887873 . The bins also work on any standard Gridfinity baseplate, in any drawer with 120 mm of headroom.

Features

• 4 footprints: 1×1, 2×1, 2×2 and 3×2 (standard 42 mm grid)

• 6 heights: 20, 40, 60, 80, 100 and 120 mm overall, lip included

• 24 ready-to-print STL files

• Standard Gridfinity feet and stacking lip: they fit any Gridfinity baseplate and stack on any Gridfinity bin of the same footprint

• On the light Küpper baseplate (no floor) the bins rest on the drawer bottom, so a 120 bin is exactly 120 mm tall in the drawer

• Stacked bins nest 4.35 mm into the lip below, so a stack that adds up to 120 stands between 98 and 116 mm tall

• 1.2 mm walls that widen at 45° under the lip, 1 mm floor above the feet

Print settings

• PLA or PETG, 0.4 mm nozzle, 0.2 mm layers

• 2 perimeters, 15 % infill

• No supports, no brim. Print feet down, as exported.

• One colour, no MMU needed.

File names

• bac = bin, then the footprint and the overall height: bac-2x1-h60.stl is a 2×1 bin, 60 mm tall.

Make it yours

• All 24 bins come from one parametric Python script (manifold3d). Change the heights, the footprints or the drawer limit at the top of the file and run it again; it checks every stack against the limit.
