This is a 160mm x 65mm x 55mm box
The pieces will slide together with registration pins and the sliding top clips closed. I designed this to hold desiccant pouches and used modifier boxes in prusa slicer to remove the top and bottom perimeters to expose the infill on each piece.
If printing on prusa mk3 or similar sized build plane it will need to be broken up into two prints probably. I would recommend gluing the bottom and sides together for durability.
Again if you want the exposed infill on the pieces you will need to use modifier boxes to remove the top and bottom perimeter layers.
I used 20% infill printed in petg
