Cabinet Door Twin Cutting Board Holster
A screw-on holster for the inside of a cabinet door. It stores two cutting boards upright, each up to 20 mm thick, in two 22 mm drained pockets, and stands just 56 mm off the door. Print two (each is 30 mm wide by 90 mm tall) and space them under the boards. Mount with #6 wood screws (3.5 mm shank) or M4 screws through the 4.5 mm holes. The part prints on its side so every layer holds the full U profile, which keeps the board weight in the strong plane.
