Edited UI walkthroughs are not real-time performance benchmarks. Rendered examples show add-on output, not physical prints; the cover is stylized artwork.

THE MODEL

One model. Focused demonstrations.

The mannequin provides context; the demos focus on a prepared thigh section. Existing mannequin joints belong to the source model.

02 / CUT

Three ways to split a mesh.

Use Straight for a plane, Freehand for a custom contour, or Surface for a closed loop. Queue and edit cuts before applying them.

03 / CONNECT

Build the connection you need.

Choose six connector profiles, including your own Custom Object. Use loose pins, attached pins or a recessed outline seam. Adjust dimensions, insertion depth and clearance.

04 / PREPARE FOR PRINT

Calibrate. Check. Export.

Print peg-and-ring samples to calibrate clearance. Inspect assembly and orientation checks, then export STL, OBJ or multi-object 3MF, with a JSON assembly list.

Included

• Mesh Split 1.1.1: legacy installer for Blender 3.0–4.1 and Extension for 4.2–5.2. Install only the matching ZIP.
• Quick start, illustrated manual, operator reference, release notes and GPL source.
• Six editable demo scenes and six MP4 walkthroughs.

Windows tests covered nine builds across Blender 3.x–5.x; exact versions and scope are in the documentation. Newer demo .blend files may not open in 3.x. No extra paid add-on or activation service is required.

Before you buy: use clean, closed meshes. Invalid geometry or paths can be rejected. Assembly checks are aids, not safety certification. Calibrate with your printer and material; slicing and printing are separate steps.
