CatPin is a new Blender add-on developed by Alex Sokol, designed specifically for preparing 3D models for both FDM and resin 3D printing. This tool enables artists to split models into segments while ensuring all parts fit together seamlessly via matching pins and sockets. Users can make straight or custom curved cuts, allowing for a high level of detail when printing objects such as figurines, statues, or busts. CatPin is compatible with Blender versions 4.2 to 5.2.
One of the key features of CatPin is the Manual Cut, which offers precise control over cutting complex shapes by allowing users to draw lines or place points for accurate cuts. The Polygonal Cut feature lets users define specific areas to be cut out, useful for creating window openings in vehicles or detailing figures’ features. Additionally, the add-on provides straightforward Straight Cut and Curved Cut options for predefined shapes.
The add-on operates in two modes: Draft Mode, which offers a fully editable, non-destructive workflow, and Easy Mode, which simplifies the cutting and connector process, making it ideal for less complex models. The recent 1.0.7 update includes enhancements such as support for up to five connectors in a single cut, a double-sided connector, and an adaptive surface feature for improved quality.
CatPin can be purchased here for those interested in enhancing their 3D printing workflow.
