Monitor Riser 150mmx160mmx40mm

I needed to free up some space on the desk for my music gear. So I made these strong brackets to get one more level on my desk. They are 150mm tall, 160mm deep and 40mm wide. They have 3x Ø5 holes for screws in them. All you need is a board and 6 screws! Let me know if you need something to be modified on it!
