Thank you to Markellov for the tile. I used it to made this box.

It's ~100x100x92mm with 3mm walls currently. Scale it to the size you need.

It should printable without support but I did not print it yet, just design it for fun.

Hint: If you are unsure maybe try wood filament in thin layers (~0.1) and print it slow and accurate. I guess it will look like clay pottery (but not sure).
