I spent hours drawing this simple, yet elegant adjustable feather wrap-around ring so that you don't have to. This goes amazingly well with the style of the boho-chic movement and will be a great addition to your product offering if flowy fabrics and barefoot Instagrammers are your jam. The file is native to Rhinoceros 5.0 (I am a jewellery designer) and it is print ready. There are no naked edges, and no non-manifold edges, and all the bits are properly joined.

Volume: 320 cubic millimeters;Estimated silver weight: 3.5 grams;Estimated gold weight (9K): 4.2 grams;Estimated gold weight (18K): 4.8 grams;Inside diameter: 17.5 mm - can easily be adjusted once cast;Metal thickness: 1.5 mm

I did not fillet the edges of the pointy bits because those will blunt themselves on the abrasives used for finishing the casting.I did not sprue the ring because my casting supplier prefers to do their own sprueing, and I assume that is the case for others as well.

Have fun!
