Chains and Meshes

thingiverse

The Simple Undulating Link Created by Function \r\n\r\nFunction F(t,h=height) =\r\n [ Cos(t), Sin(t), H x Sin(2*t)];\r\n\r\nCan Be Connected in a Matrix to Form a Chain or Mesh. The Openscad Code Previews Quickly, But Rendering is Slow Because Each Link Added Must be Checked for Intersection with All the Others, Leading an O(N^2) Performance. \r\n\r\nMost Chains I've Seen Use Flat Links, But This Curved Link Allows a Flatter and Uniform Mesh Because the Link Works Bidirectionally. Some Chain Mail Uses a Form of This Link, But Openscad Allows the Shape of the Link and Its Orientation to be Parameterized.\r\n\r\nTo Make the Mesh More Printable, Subtract a Base Positioned Below the Links to Flatten the Feet of Each Link.
