Penguin On Ice

myminifactory

"Penguin On Ice" is my 3D printed interpretation of JKBrickworks "Penguin On Ice" Lego model. We enjoyed their model so much, I decided to design, 3D print and assemble this non-Lego version. Both models utilize a "Trammel of Archimedes" mechanism which utilizes "channels", "shuttles" and "link arms" to generate the penguin motion (see the "Penguin On Ice Mechanism, CAD View" video). The channels, shuttles and upper link arm in the JKBrickworks model are exposed, but in this model, the channels, shuttles and upper link arm are hidden beneath the cover build plate side "ice surface", and the penguin, magnetically coupled to the upper link arm, appears to skate on a smooth surface of ice. For the model to operate correctly, the cover ice surface must be glass smooth. As I 3D printed mine on a glass build plate, mine was smooth without any further finish work required. But your cover may need sanding and polishing to attain the required surface if 3D printed on a non-glass build plate. As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes. Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA on Ultimaker S5s.
