Homemade French cleat workshop small part storage board

Homemade French cleat modular storage board. 42" x 24" board with 10 French clear board rails. 10 movable French cleat boxes in a couple sizes. Storage board has two french cleat type mounts already attached to the back or screw it directly to wall for more permanent fixture. I planned to build many more boxes of different sizes for maximum modular small storage but project stalled out 😞 My loss is your gain
