The cross hatched air slots look nice, but are fragile and broke quickly.

Revision 2

The second revision was directly planned in the vector files - the model didn't get an update.

The size was substantially increased to make plugging USB cables possible. An active heatsink was added increasing the height of the case.
The case was painted and received more attention to details. To prevent scratches and marks I added small bumpers with a glue gun. The hinges were replaced with metal ones and the case layers were glued right from the start.
