This model is a facade maquette from an art nouveau styled house, build in 1912 (presumably) in Geel, Belgium. It's easily printed flat on it's back. It's a long print, but the result is gorgeous when placed in a frame against the wall. Or you can also simply put it on a shelf.
It's 24cm x 20cm, but you can scale it down. You might want to adjust your layer height in an equal percentage so you don't lose the details. Or you can scale down the XY size, but keep the Z.
The frame I used in the picture is 40cm x 50cm with a 30cm x 40cm passe-partout in it. If you have questions, do ask!
