This is box/ organizer for cosmetics in bathroom, It have honeycomb bottom and can be use with wet items.

there are small hols on each corner from top and bottom to connect 2 or more together (for connection there are to small ‘hooks’ - flat is for bottom and with ‘handler’ from top.

connection is quite easy; just press the hooks into holes, but if disconnection is needed, start with top one pulling by the handler and then you can easy disconnect bottom.

I printed it with 0.4 nozzle and o,2 mm high with petg. 

probably I would decreased printing speed to improve rungs print quality.
