Made some coat hanger tablet stands in another post using coat hangers, I wanted a stand that would be less likely to damage a touchpad and be easy to store while traveling. This what I dreamed of after seeing another idea.
Draw your pattern.
Trace it over two pieces of thick posterboard.
Cut out the pieces. (Just using one long piece is hard to fold.)
Double tape the backend of the two pieces together.
Bend and insert your tablet.
Update: yet another prototype stand. It did not work as expected, but worked well enough.
