I've printed with some supports to make sure it would word. Besides that I printed with a super slow speed (50mm/s) and 0.1mm (layer thickness). Took me about 9h printing.
I'm pretty happy with the result. However it's quite heavy, forcing the carriage, specially if you install a bed leveling sensor (I gave up, btw).
I'll try some simpler model, with no support for the auto bed leveling. I don't think it's really necessary.
