Here is a full model of a hidden blade inspired by the Assassin's Creed series. The harness, which also holds the model together, is available here: http://tinyurl.com/c8rgsgo Full credit to the man that came up with this design, Ammnra. And to the man that I based my design off of, Brambolo.

No robotic avians were harmed in the making of this product.

These earrings are sized for 18 gauge piercings. They should fit most people with pierced ears, but if you need a smaller gauge, check out the fishhook version in my shop.
If you need a larger gauge, just ask and I can resize them for you. I will continue to add other sizes as I make them.

Disclaimer on the images: any photos labeled "polished" are stainless steel that has been hand polished with a dremel. The stainless that you order will have more of a texture to it. I haven't yet made these for myself in bronze glossy, gold plated glossy, or either types of silver, but if you want the highly polished look your best bet is going to be silver glossy.

Celtic knot rolled round to create a ring, making quite a balanced design. Made from a knot with 20 loops and seed 1 using the Knot application.

The diameter of the ring is 16mm on the inside (size 5½/K½). Send me a message if you'd like me to create a different sized version.

This is part 2 of a snap-fit puzzle machine.  When you turn the knob, it generates fun!  This is the deluxe model, there's a smaller version here.

NOTE: The silver piece shown in the pictures was NOT printed by Shapeways. It was printed in Frosted Ultra Detail, which was then used to make a mold which was used to hand-cast it in silver. I haven't printed it in silver, so I can't vouch for how it will turn out.

  This ring a little more decorated than Ring_01. Instead of all the little squares ordered in one direction, there is every other square one square added and turned 90 degrees.
