Model Splitter

Model Splitter cuts 3D models into parts you can print and fit back together.

Draw a seam on the model where you want it to come apart: a straight line, a band around an arm, or a painted area. Model Splitter cuts along it and adds pins, push-fit joints or magnet holes so the parts line up when you glue them.

Use it for figures, props, cosplay, terrain, vases, car bodies, or any model that will not fit your printer in one piece, or that you want to print in several colours.

What you can do:

• Cut along a straight line, a plane, a drawn band or a painted area
• Add built-in pins, loose tenons, push-fit joints or magnet holes at each cut
• Split a whole model automatically into parts that fit your print bed
• Inlay and insert parts, such as eyes, for multi-colour prints
• Pose figures: paint a limb and turn it at the joint
• Repair holes and reduce detail on heavy scans
• Export STL, 3MF and a printable assembly guide

It works offline once it has started once, opens STL, 3MF and Model Splitter project files from your file manager, and keeps itself up to date. Every cut happens on your computer; your models are never uploaded.

Free: Straight line and Plane cuts, repairs and export, with no sign-in and no time limit. Pro tools are open to everyone until Pro goes on sale.
