Personal Storage Box

A Personal Storage Box is a small container for storing items. It does not have any belt connector, thus it can only be accessed by engineers. It has 25 storage slots for items and uses 2m³ of space, which its volume is only 1% compared to the Storage Container, making it considerably more space-efficient.

Trivia

 * The Personal Storage Box can be stacked vertically, 1m apart from each other. Construct some stacked 8x1m foundations, build the upper storage box then deconstruct the upper foundation. Build the lowest storage last.
 * It has 1 more slot compared to the Storage Container.
