thingiverse
This is the one piece version of the 2 part box (https://www.thingiverse.com/thing:4965356) If the customizer doesn't work to set your custom box number, download the .scad file. Open it in your favorite text editor and change the line at the top box_num = 666; to your own number. If you got a roman numerals one use quotes: box_num = "XX"; Save the .scad file and use an online scad to STL tool to get the STL for printing. 23Sep Changed the scad file to better scale custom box numbers - also removed the setting so you can enter any text (e.g. if you got one of the roman numeral boxes)
