Small sample box

A 50x50 mm sample box which holds 20 samples which are 12x7x1.5 mm^3 in size or smaller. Grooves between the slots allow for easy access with tweezers.

The box and lid are printed with the outer side down and with a reduced number of outer walls so that the small grooves on the outer surface are completely bridged by the above layers.

The holder is printed with a single outer wall, no infill, no top or bottom layers (or vase mode with no bottom).
