Pizza-plate-in-cupboard holder

I wanted to have all the stuff on top of my microwave gone, including a 38cm-diameter 1.5cm thick pizza plate which didn't fit into my cupboards. So i made a little holder which holds the plate diagonally so it -just- fits in the cupboard.

It's designed for a cupboard-shelf space of 27cm height and 31cm depth. So if your cupboard has those dimensions or larger, then you can use this part.
