What a ikea lack wall-shelf hidden bracket is
A hidden bracket that replaces the stamped LACK shelf hardware with a 120 × 20 × 16 mm French-cleat style plate so a 110 cm LACK shelf sits tighter to the wall. Two 4.5 mm holes sit on 80 mm centres. Print in PETG with 3 mm walls.
The bracket cover hides the official plate; this replaces it. Describe shelf length in SpeakCAD, preview the bracket in the browser without paying, then download the STL.
