"Blade Runner" Ennis House Tile
by Keenan, published
This design is most famous for being used in the sci-fi classic film "Blade Runner". It was originally designed by Frank Lloyd Wright for the 1924 Ennis house in Los Angeles, where the design was used on repeating concrete blocks.

You may get warping if you don't use a heated build platform. The default STL is 145mm square, but scale it as you choose. You can also scale the z axis independently to get more or less releif on the tile. The sketchup file is included.
I realize there is already one of these on Thingiverse, but I drew this one independently and it is slightly different and I think slightly more accurate.
