Well the truth is I made a mistake with the reference size of my printer, so this part came out smaller than Petals1. But it printed in only 6 3/4 hours using a layer height of 0.200 mm and a print speed of 90 mm/sec. So I thought I'd publish it anyway.

I have corrected the error and will be publishing Petals3 tomorrow. It really will be larger and easier to print that Petals1. But the estimated print time is around 10 hours.
