Kindle, smartphone and tablet stand. 30°, 45°, 60° and 90° angles possible. Very easy to carry. Different tickness available (9, 10, 11 and 12mm). Measure the tickness of your device and choose the corresponding STL file. For kindle paperwhite use the 9mm tickness. Tips: I use it to read with my kindle paperwhite in my bed with the device in "landscape" position. Not an efficient method to read but an efficient method to sleep :)
