Update at 12-Sep-2016:
Some further research showing that most Peg Board accessory available in Thingiverse are designed for peg board with thickness 1/8 inch.(Type A in Wikipedia). So I modified my design to make good use of existing open-source design.

Actually I want to buy it, but unfortunately I cannot find it from any store in Hong Kong......
With a 3D printer , I guess it is not very difficult to fabricate some of them.

This is designed to be glue together and mount to shelf by Zip Tie.

It was made according to the Type A and Type B standard specified in Wikipedia.

Although they can hold together by friction, I recommend fixing them by epoxy for high-load situation.
