Stand for Ereader or tablet

Recently I desired a stand to put my E reader on to free my hands. I've searched a bit on Thingiverse but didn't really found something to my liking, (maybe I did not search well enough).
After 10 minutes of searching I decided to design my own and voilà.

To different angles, One at 20 degree and one at 35 degree.

These fit a sony ereader with case with light with ease and I assume that almost any Ereader or tablet will fit. In case it does not fit, just scale up or down :)
