Cut in pieces. It should stand 17cm tall when print on a Form 2 at 50 microns resolution (yeah, 50... microns... that's the diameter of a human hair, so I'm excited to see how precise that thing is). Since the Form 2 printer is comfortable with big files until around 1 million triangles, I did my best to optimize the density of the mesh so the outer surface is way more dense than the inner part.
