Sturdy Toothbrush Travelbox

Do you know those travel boxes for toothbrushes? Those that you put in your bag the day when you go on holiday, and once arrived take them out in a hundred pieces again? Or those that survive a journey but when trying to clean them break apart?

Well I wanted to have a toothbrush travel box that will survive both traveling and cleaning, so i designed a pretty sturdy one!
The walls are around 3mm thick, so it is not geared towards low material consumption.
It has small holes in the bottom par
