Liked the design from @TheSameNameTwice, so I remixed it improving and reducing some weak points.
 

1. Top cover improved closing latch:

The lever is now longer, to have a smoother closure and more durability. Moreover the latch has a 'B' structure to support flexibility without breaking easily.

2. Bottom box has three improvements:

• The hinge is supported by three sturdy and smooth inserts coming from the bottom, increasing durability and avoiding breaking it during first assembly.
• Additionally I carved a V shape insert area to have a better hinge snap-in during assembly.
• Finally the front latching area is now improved a little because it was too thin in the original model.

Printed with tree supports to improve plastic structure but they may be not used.

Suggested a flexible material like PETG to ensure a better assembly of the hinge.
Bottom box can be printed in PLA, but cover is recommended in PETG.
