Easy Slice Documentation

Easy Slice cuts a mesh into two printable parts and builds a matching joint key so the parts snap back together. You draw the cut right on the model.

1. Installation (Blender 4.2 or newer)

1. Download easy_slice_1.0.0.zip. Do not unzip it.
2. In Blender, open Edit > Preferences > Get Extensions.
3. Open the dropdown at the top right and choose Install from Disk...
4. Select the zip file. Make sure the add-on is enabled.
5. In the 3D Viewport, press N and open the Easy Slice tab.

2. Before you cut

• Select the mesh you want to cut. It should be a solid, closed mesh (no holes).
• Apply the object's scale (Ctrl+A > Scale) if it is scaled.
• If you plan to use millimeter fit, scale the model to its real print size first.

3. Straight Cut

1. Select your model and click Straight Cut.
2. Drag a line across the model in the viewport.
3. The model splits into two parts with a joint key built in.

Press Esc or right-click to cancel. If the line is too short you will see "Drag a longer line."

4. Surface Cut

Use this for curved cuts and cuts that follow the surface, such as around an ear or along a panel line.

1. Select your model and click Surface Cut.
2. Click points around the part on the model.
3. Click and drag to make a point a curve.
4. Click the first point (or place the last point near it) to close the loop.
5. Press Enter to cut.

You need at least 3 points. If the line would leave holes (for example through a thin part like an ear), Easy Slice stops, tells you why, and keeps the tool open so you can fix the path.

5. Joint Key

After a cut, select one of the two parts. The panel shows Cut part selected, and the Joint Key and Fit settings update the joint live. Turn Joint Key off to cut without a key.

6. Fit

Print a test piece first. Printers differ, so adjust the gap if the fit is too tight or too loose.

7. Working with your parts

Select either part of a cut to see these buttons:

• Explode / Assemble: move the parts apart to check the joint, or put them back together.
• Undo Cut: remove the cut pair and bring back the original model.
• Apply Joint: lock in the joint as it looks now. After this the pair can no longer be edited with Easy Slice and the hidden backups are removed.

Output settings

• Original: Delete (replace the original, Ctrl+Z brings it back), Hide (keep it hidden in the Outliner), or Keep Visible.
• Explode After Cut: spread the parts apart right after cutting.
• Clear Backups: permanently delete the hidden originals kept for Undo Cut. Cuts made before can no longer be undone.

8. Tips

• Cut away from thin areas such as ears, horns or thin plates.
• For long models, make several cuts and use 2 or more keys on round pegs.
• Use Explode to check the joint before you export.
• Export each part as its own STL and print it with the cut face on the build plate.
