This oval bowl/container with lid is actually a modification of https://pinshape.com/items/290.... I used an ellipse instead of a heptagon for the outer shape and increased the overall size so the result would hold more stuff. I printed both parts with a layer height of 0.200 mm and a print speed of 100 mm/sec. The bottom printed in 25 1/2 hours and the top, which needs no supports, took 16 3/4 hours.
