The ultimate 3D printing & hard-surface workflow extension for Blender. Draw precision cut lines, split complex geometry cleanly, and generate watertight male-female dovetail keys in one click.
Stop manually building alignment pins and key sockets. Cut & Key automates the entire process in two fast stages.
Draw straight or freehand cut strokes across specific parts of your model. Cut only what's under the stroke while preserving smooth & sharp shading boundaries below 30°.
Instantly generates interlocking male pegs and female sockets between selected split halves with adjustable scale, height, taper, and direction flip.
Built-in planar ngon hole fill & beauty triangle fill algorithm automatically caps open boundary cuts, making your parts immediately watertight for SLA/FDM printers.
Need to re-adjust your cut placement? Instant 'Undo Last Cut' and 'Delete All Cuts' tools keep your original topology safe and clean.
Try out the exact parameters and workflow of the Cut & Key panel directly inside this interactive 3D visualizer!
Draw a cutting stroke anywhere on your screen. The addon project-slices only the faces beneath the line, retaining sharp bevels and smooth surfaces effortlessly.
Generate trapezoidal dovetail keys designed specifically for FDM and SLA 3D printing tolerances, eliminating glue alignment issues on large multi-part prints.
Instant digital download available on Superhive Market with lifetime updates and full support.
