Small sample box

A small box (50x50 mm) for small samples (12x7 mm).
Indentations between the slots allow for easy tweezer access.
Indentations around the outside of the box and lid let the holder snap into place.

The holder part is printed with a single wall, like vase mode with no bottom or roof.
For the box and lid it is important to make sure that the outer indentation is bridged properly by the next layer. Usually I do this by limiting the number of walls to 2.
