finvase3

This part printed in slightly more than 14 1/2 hours using a print speed of 100 mm/sec and layer height of 0.200 mm. The basic shape is made by revolving a circular arc, adding the bumps which are elongated spheres, and then intersecting that with an array of rectangular fins. The design has a lot of small repetitive detail, so a successful print requires a printer that can make accurate moves.
