Introducing the COCRE HUB Case Collection 2025

80 new cases were added in 2025 to "COCRE HUB (Kokuri Hub)," the platform for making self-help devices with 3D printers! We will explain the background of the new Case Collection of self-help device 3D models, all of which can be downloaded and used for free, introduce its categories and items, and guide you on how to use it effectively. It is actually very useful even if you don't own a 3D printer!
