A4 paper holder

For office work, I often needed to copy things from paper to my computer. More often than not, these papers have been folded, making other paper stands useless because the top falls down. This thing was designed so that it's easily moved in a bag without taking up much space.

besides printing the parts, you also need to cut a 16mm diameter PVC pipe to your preferred length and get a small paper clamp for holding the paper.
