It's a simple, small (20g), stand for phones and tablets, with 4 different angles.

It was designed for a Kindle Fire which is 9.6mm thick. For different sizes you could just scale the whole thing by (device_width/9.6*100)%
It works as-is in landscape mode - print and attach two legs for portrait mode (at least for the highest angles, or it will tip over)
