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. The gcode is there, but there are the other files. Originally done in Rhino for Mac. Prints six clips, two sets in total.
