Thingiverse maker jtbowden created the beautiful "Turk's Head Knot". This design caught our eye not only because it's visually attractive, but also for two other reasons.
First, this design should be very easy to 3D print even on the most basic 3D printers. Some designs can be quite aggressive and require particular resolutions or complex support material, but this item should print quite nicely.
Secondly, we're fascinated by how the model was created. Apparently jtbowden generated the model by programming Google Sketchup:
The knot path was generated via a Sketchup ruby script I wrote, and then the strand cross-section was extruded along that path. This created some very complex objects and took some work to figure out how to deal with overlapping areas and get a manifold object.
If you'd like to nominate a design for next week, please let us know.
