Ugly Ducklings

This CAD model was designed by Oskar van Deventer, copyright (c), 22 February 2025.

Ugly Ducklings is an invention by Volker Latussek. When I was working on Volker's Duck Stew puzzle, I made a mistake and I 3D-printed a whole bunch of ducks of the wrong shape. I asked Volker whether he could rescue these ugly ducklings. Within a few hours, Volker proposed to put a lid on the box with a square hole. The object is to insert the seven ugly ducklings. Surprisingly, there is only one solution.
