Picture of How to tie a Turk's head coaster using a 3D printed model
Tying a Turk's head knot can be tricky without something to follow along with, especially when you want to get more complicated than the standard 3 part x 5 bight ones you can find instructions for online. I generated a 3D model of a 6 part x 7 bight Turk's head and used it as a guide to actually tie the knot. I'm working on an app which will allow you to generate any Turk's head in any size, but for now all I have available is this single test model.

Step 1: Materials

Picture of Materials
1. The model

I had Shapeways print my model, which can be ordered here: http://www.shapeways.com/model/983341/nautical-themed-rope-coaster.html

I ordered the alumide material, but any of them will do.

2. A cardboard box

We'll be temporarily attaching the model to the box to hold it still while we tie the knot.

3. T-pins

The pins both hold the model in place as well as serve as something to keep the rope in place with once we start tying the knot.

4. Rope

I'll be using 1/8" cotton rope while I walk through it. It's a bit thick for this particular model, but it's great for knot tying in general! I ordered it from Knot and Rope Supply: http://knotandrope.com/store/pc/1-8-X-1-200-3-Strand-Cotton-6p1936.htm

Feel free to use whatever material you have, though you probably want to stay at or under 1/8" for this model. I think smaller material looks better as you can tie more passes. The red coaster shown above is tied with lacrosse crosslace and comes in many different colors: http://www.lax.com/lacrosse-equipment/Lax.com-Crosslace-Spool-Lacrosse-String-Supplies-4157.html

Sweet! Thanks Ayesha, glad you like it :)
Interresting design, thanks for sharing!

But I wonder, wouldn't the same be possibly using a print-out of such a coaster for the pin-placement? Just wondering whether the 3D-print is strictly necessary for those who do not have access to such a device.

Yes, absolutely! For this example especially. The 3d print is just a bit more sturdy and reusable. Also, this really was a test for my app, which will be able to generate a variety of turk's heads, such as ones that cover a sphere or even a cross. In those cases it's much trickier to just use a printout (though, still possible). The 3d print is really just a convenience.

If you're interested, you can check out this facebook album which shows me using the same technique to cover a sphere. The 3D print is especially handy in this case: http://on.fb.me/10panyF

How long was the rope you used for this model? The coaster is not the model, correct?
allwinedesigns (author)  Soozannah6 years ago
The red one with 4 passes, tied with lacrosse crosslace is about 18 feet long, so I'd cut a 20 foot piece to tie it. In the 1/8" cotton, you'd probably be safe with 12 feet, though I didn't measure. When I say model, I'm referring to the 3D printed version of the knot, the coaster is what I tied using the model as a reference.

This is a cool use of 3D printing, thanks for sharing!
