I wrote about a stand that I made in one hour here. It took a bit more to do this one in my friends workshop (needed some joiner's tools to drill holes in a proper angle). The frame is made of oak wood, I used 6mmx16cm long screws and a really good glue to put it together. The aluminium trim is screwed with 6mmx6cm long screws. The laptop just slides in so it doesn't move around. I used the white platform from the old stand (hence so many holes).
