This is my 4th iteration of SquircleBowl1. #4 uses a pentagon as the basic shape generator, but I added 2 twists - one clockwise and one counterclockwide - to create the final result. Read more about twisting things here: http://birkbinnard.com/blog/do-the-twist2/.

This part printed in 20 3/4 hours using a layer height of 0,200mm and a print speed of 80 mm/sec.
