One-hand reading clip for Kindle Paperwhite (could be modified for tablets)

Holding a screen that wide, however light, is uncomfortable for me. I prefer using one hand. Before knowing how to use a 3D printer, I used a rubberband corner-to-corner.

Three clips and a rubberband are all that are needed. The bottom two do tend to slide inwards, but I'm satisfied enough. You could always modify the hooks on those two to angle slightly.
