Brackets for Small Shelves

We were looking for a way to open up some cabinet space and improve our kitchen so I designed some shelves for spices. 

The brackets are printed and secured to the wall with finishing nails.

The shelf material is some scrap material I had laying around but you can use just about anything as long as it can support the weight of whatever you intend to place on the shelf. Depending on what you intend to use, you might need to scale the brackets to fit; the depth of the shelves I used was 85.5mm which can be used to determine the scaling factor.
