Printed in black ABS. 20% fill, 120mm/s. top and bottom took about 18 hours each. Destroyed the kapton getting the bottom off - so much surface area in contact with the platform! Top was easier (the opaque file) to get off, only a little kapton scuffs. The thing looks beautiful! But, the bottom of the petals seem to be fused together and won't open. Trying some careful work with a x-acto knife, but no luck yet.
