Celtic3d Knotwork — an add-on for Blender

Real Celtic knotwork for the things you make.

Set out a grid, place the breaks, and the knot draws itself — strands weaving over and under the way the Pictish carvers laid them out. Then export a file your 3D printer, laser cutter or CNC router can make.

The Ulbster cross, a bundled knotwork pattern rendered by Celtic3d Knotwork for Blender

Ulbster cross — bundled pattern, after Bain

Built by the book

Constructed by George Bain’s method — the grid of dots, the plait, the breaks that turn a plait into a knot — extended with Aidan Meehan’s secondary breaks. Every bundled pattern names the plate it follows.

From screen to workshop

Full over-and-under weave for 3D artwork, or carved relief on a base plate. STL and OBJ for printing and CNC; SVG outlines in millimetres for the laser — unedited, straight from the add-on.

Free is complete. Pro goes further.

Free: flat panels, borders and crosses, both break types, weave and relief, every export, commercial use. Pro adds rings, cylinders and toruses and more strand profiles — £25 / $34 for the first year, three machines.

Ten bundled patterns, each cited to its plate
