MeshPrep Pro splits your .3mf and .stl models into parts that fit on your print bed. It adds the connectors that lock the pieces together and makes a step-by-step assembly guide, so the finished print goes together right the first time.

Free forever. Every feature included.

How it works

Four steps take you from one model that’s too big to print to a set of parts that snap back together.

  1. Mark your cuts

    Open a .3mf or .stl model and place cut lines along X, Y or Z, by hand or with Auto. Name each cut, like head, waist or left arm, and lock it once it’s where you want it.

  2. Choose the connectors

    Pick round, square or quad pegs, or pockets for magnets. Go male/female, or female/female with matching dowels printed as separate parts. Then set the peg size and how tight it fits, from a press fit to a loose one.

  3. Slice it

    Press Slice and the model splits into separate parts with the connectors already built in. Touching pieces get different colors so every seam is easy to see, and the Explode slider spreads them apart for a closer look.

  4. Print the guide

    Save an assembly guide as a PDF, in landscape or portrait. It shows every numbered piece from two sides, lists which ones join, and walks you through putting them together.
