This is a very useful screwable soap box for traveling and so on.
In this box you can put in soap with a diameter of 50 mm and 10 mm height. It is very spartan - it has no sharp edges or pattern. So it is easy to clean hygienic.
It has a mesh and a drain to hold the soap really dry! If you close the lid, then the drain is also fully covered.
When finished my design, I found out that there is another box already publish with the nearly the same idea but without a drain.

I printed my box with PETG for outside use or traveling in a hot car. I choose white to see every dirt when cleaning.
