Kickstand?

[tppytel]

I'm not generally too bothered by the Prime's upside-down screen polarizer, but it's occasionally annoying when I have a lot of calculations to do on a crowded desk where it's hard to look right down at the screen. I know there are some larger 3D-printed desk stands out there, but I move around a lot and would prefer something more portable. Has anyone tried any of the various phone kickstands out there? Most of those clearly aren't designed for the stability you'd want for punching in values on the Prime's keypad, but I'm thinking that a smaller one might be stable enough to get me 20-30 degrees for better brightness and reduced glare from overhead lights. Maybe just one of the simple ring stands would work? Might need a little improvisation with some extra rubber feet so that it could still sit relatively flat without the stand extended?

I figure someone's probably tried this, so I should ask before sticking gooey things to the back of my Prime.
