This is a quick prototype of a pierogi press I designed using Alibre, the first time I’ve done a multipart confined assembly, where the moving parts are printed in-place locked together. The hinge pins are printed inside their holes so the finished result is preassembled and doesn’t need any screws or fasteners. For those not familiar with pierogis, they are sort of a Polish dumpling/ravioli food, a pasta-like dough usually filled with a mashed potato type filling.
