What is ZZ Mesh?

ZZ Mesh is a browser tool for splitting a 3D model into pieces you can print and put back together. You load an STL, OBJ, 3MF or GLB and pick one of three cuts: a flat plane to make a tall print fit your bed, an organic cut you draw along the surface so the seam follows an arm or a cape, or an extract that pulls out a part such as the eyes to print in another color. An "I'm feeling lucky" button finds the natural parts of a figure, such as the head, arms and legs, and splits them in one click. Connectors can be pins, dovetails, puzzle joints or magnets, and every piece comes out as a closed solid, ready for the slicer.

The same site has a few more tools: 3MF to Parts turns a painted 3MF into one sealed part per color, so you can print it without an AMS; Piggy Banks hollows any model with an even wall and adds a coin slot and a screw cap; Figure Bases makes a base with pegs under each foot and the figure's name engraved; and STL Repair closes holes and fixes flipped normals. There is also an OrcaSlicer plugin that sends a model from your plate and brings the parts back.

You need a free account (Google sign-in), even to try the example models. The free plan gives 30 credits to start and 5 a month, for models up to 600,000 triangles. Credits are spent by the triangle count of each part you cut.
