Puzzleurprint is a Blender toolkit for slicing large 3D models into smaller parts that reassemble after 3D printing. It generates objects called Connectors, which cut objects into pieces and add elements for putting them back together. A consecutive parameter system lets you adjust connectors, recall the settings of connectors you have already created, and copy or paste settings between different connectors. A gizmos system handles most parameters on the fly.
Planar connectors produce jigsaw puzzle-like structures, with 16 connector shapes and a stopper option that keeps connectors on the backside while leaving a straight cut. You can move into 2.5D, cut sculpts for 3D puzzles in the z direction, or use large and light panels behind an oversized print. Cylinder inlays with a plane cut or joint cut make heads, arms, tails and mouths moveable for action figures, and it can play an animation before the first keyframe.
Reversible wall mounts hang items like TVs, instruments and cupboards, using planar connectors with the stopper active to slide into a fixed position for a safe connection. Puzzleurprint supports Blender 2.92 through 5.0, is distributed under the GPL license, and includes a tutorial and a demo video.
