Stackable Boxes in different designs, 196x136x47mm

The boxes were printed in PLA with normal settings (.4 nozzle, .2 mm layer).

The plain box was printed in transparent PLA with Gyroid infill.

The pillars box may need some support or not, depending on your printer. Decide at own risk ;)

The pearls box was changed from the print in the picture to make it printable without supports.

The other boxes really should not need any supports. The slot on the underside for stackability printed just fine without supports for me.
