Teleprompter for 5x7 glass
thingiverse
I designed a thing for larger glass, but I realized if you use your phone or tablet for your captions you may not need such a large one. So go to your dollar store, get a 5x7 frame, take out the glass, and you're on your way. Use 1/8" bolts in the holes to hold it together. That makes it foldable and storable! I usually design in metric, but for this I had to use inches. Scale up by 2540% to convert from inches to millimetres. I haven't printed this up yet, so I've marked it as a WIP.
