This is a cool little desk ornament. It could also be used as a decoration on a shelf or some other location. The surfer balances on one side and the shark on the other. For assembly instructions look to the photos or the documentation area where the same photos are. There may be other settings that work, but the settings that I used for printing all the parts where 0.2 mm layer height, 20% infill, and 2 walls. All being printed with the same settings allows all the parts to be printed together. There are also built in brims around some of the points on the models. The brims need to be removed after the models are printed. If the main spinning part is not level, then either the surfer or the shark need to be slid down. This model makes a great decoration or toy that looks cool and interesting, and actually can move and do something. I hope you enjoy the model and have fun with making it.
