Samsung Galaxy S4 mini cover with thicker walls

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!
  Please read instructions before printing!!
  Hope you enjoy!
  Tell me if it works for you!!

  Thanks goes out to elgrande!
