French cleat shelf brackets (18 mm)

French cleat shelf brackets for 9mm boards and 18mm cleats. 

The brackets are 200mm deep and you can choose your width as you like. The shown shelfs are 400mm wide.

To attach the board I use 3x30 wood screws.

Also available for 15mm french cleats: https://www.printables.com/model/1231634-french-cleat-shelf-brackets-15-mm
