I promised an update from an other cover from me: http://www.thingiverse.com/thing:357994
##Updates are:
- thicker walls
- holes for cam/flash and others are at the right place
- added speaker and mic holes (just forgot them...see thingdescripton:357994 :-D )
- better accessibility for the power and volume up/down keys
- earplug hole is a little bit bigger and at the right place
- and little other stuff
- the pictures above are before some updates!
