The pumps on the Sultana are quite beautiful, particularly in the long curve of the handles.
Here is the initial 3D design.
I 3D printed parts, painted them, and tried them out. They were good, but looked a little too tall. Also, the interesting transition from octagon to square at the bottom wasn’t distinct enough. I revised my design and created a new set. The old version is on the left, new is on the right. The new pumps also have wire out the bottom to help hold them in place.
Here are the pumps installed on the deck.
