I have tested it with the face of Mars, with a 7x7 puzzle. It works quite well:

Unfortunately, the licence of that thing doesn't allow me to publish derivatives.
[2020-04-06] The Customizer in Thingiverse is still using the very old 2015 version of OpenSCAD, which has many flaws. I had to fix the generation of random numbers because 2015 round the seed number to the nearest integer.
