I decided today that I needed a shelf in my "office/workshop" (ie gap between the shelves). As I only have on actual wall I had to hang it from the back of the industrial racking with custom made shelf brackets - To the laser!.
Made from 4mm laser ply I am not sure how long they will last (4mm not enough, 8mm too much) but they are functional for the weight of stuff I need to add. I will re-cut them when I get something thicker to cut them out of. For some reason I tried to make them look pretty with flowers on but I don't think I will bother next time, I am not really a floral kind of guy.
