I'm a big FLW nerd, so it was good to find this model. I chose to hit it with a couple of coats of Rustoleum Filler Primer, and then some Krylon DIY Series Fine Stone Granite Texture Paint.
I also did a similar make of the Freeman House tile: https://www.thingiverse.com/make:542022
Chose this print to use Cura's "ironing" feature to create nice, smooth top layers. With a few minor glitches, it worked very well.
