IKEA SKADIS rack with hooks

I use it on my SKADIS peg board to store coffee beans and espressor cups. 

You might imagine any other way to use it as a cupboard, shelf, whatever.

All you need is a 120mm wide (wood) board which can either be layed or glued onto the shelf. I used 2x 60mm wooden boards. You can optionally add a 8mm tube or bar and attach the hooks prior to assembling everything. The holes are designed as a pressfit, I adjusted the tolerance within my slicer to properly fit the tube.
