From Thingiverse.com:

This is a case model for the cheap 7 inch monitor kit found on sites like Banggod (look for Raspberry Pi 7 inch HD LCD Screen 1024 * 600 Display Module Kit) or Aliexpress.

Printed in PLA, the top face down no supports, the bottom face up with supports everywhere.

Edit:
Added a new version for the back cover that accommodates the button boards with IR led for remote control.

Edit2:
Added a new top cover (7InchMonitorCase_Top2_touch_sensor.stl) that includes some extra 2 mm space if you want to include a touch sensor in front of the display.
