During my school years, I had a disassemble book stand. It was a handy thing: it was lightweight, took up little space and besides, there was a ruler on one half and a protractor on the other. I reproduced the stand in a simplified form (without a ruler and protractor). Added a couple of ribs for greater rigidity when assembled.
