I needed a clever solution to store organiser boxes in my workshop and was looking for a wall mounted solution. The existing “caddy”from the producer hat many shortcomings. The bars holding the organizers would give way if the boxes where to heavy.
 

So I designed my own solution. My organizer boxes are from Keter and called "Organizer Caddy XL" avaoilable through many german DIY stores. Their size is 375 mm x 50 mm x 225 mm.  But it will work for many other boxes as well.

There are 4 different parts to the Shelving System (You will always need multiples of 2 per part):
- Main part (dark blue), holding the organizer box.
- Vertical spacer (red) to connect to more main parts or to the end bracket
- End bracket(light blue), if you have an even numer of slots
- Horizontal spacer, to connect the main parts or end brackets
