There is no complexity to can not be printed easily. Box resolution can be 0.3mm, or higher for faster print. You should rotate the pin for easy print or leave it for more durability against hits but will need supports then. Also Small one for rare usage is available in the files.

Edit: I ve printed small and bigger one many times. The pin will break one way or another if printed vertically. Should be printed horizontally. Or you can do try and false.

PLA and PETG are both fine but PLA has some warping issue if you put hot coffee pulp inside the box, also not suitable for washing machine. So PETG is better and recommended.
