Split big 3D models into printable parts with alignment keys built in. Master Cutter is a desktop tool for cutting statues, cosplay props, figures and terrain that are too big for your printer. It adds dowels, pegs or magnet pockets so the parts line up perfectly when you assemble them.
What it does
-
Planar cuts: slice along X, Y or Z, with position and tilt control.
-
Natural cuts: click an arm, leg or neck. Master Cutter finds the thinnest way across and cuts straight through that limb only.
-
Curved seams that follow clothing: follow a hem, belt or cuff automatically, or click your own seam around the model. The seam snaps into creases in the surface, so the join hides along natural lines.
-
Alignment keys: separate dowel pins, built-in peg and socket, or magnet pockets. Choose round, square or hex, with adjustable size, length, clearance and minimum wall thickness. Keys are placed automatically or by hand on a live view of the cut face.
-
Safety checks: warnings if a key would break through the surface or sits on a steep part of the seam.
-
Handles big meshes: tested on a 5.2-million-triangle, 1.6 m statue. Very dense meshes are simplified automatically to within 0.05 mm.
-
Export: one zip with an STL for every part, a print-ready plate of dowels and assembly notes.
What you get

Requirements
- Desktop Chrome or Edge (Windows, macOS or Linux)
- 16 GB RAM or more recommended for large models
- Watertight (manifold) STL or OBJ files. Use your slicer's repair function first if needed.
