One of my favorite things about 3D printing my jewelry designs with Shapeways is how easy it is to experiment with different materials to determine which characteristics best serve a particular design.<\/p>\n

In this post, I\u2019ll lay out\u00a0an easy approach for creating the Simplest Hoop Earrings Ever. This minimalist style is already trendy in its own right, but it also serves as a great foundation for personalizing the design with digitally sculpted details, 3D printed dangling charms, or anything else you can imagine. And I used Rhino<\/a>, but you can follow this recipe\u00a0using any 3D modeling software.<\/p>\n

Consider the classic hoop earring:<\/p>\n

\"Sketch<\/p>\n

If we were to 3D model the seemingly simple hoop earrings shown above, we would probably need several rounds of prototyping to get the hinge and clasp to function as planned. And if we were planning to 3D print the hoops in a more rigid material like Frosted Ultra Detail<\/a> or Strong & Flexible plastic<\/a>, there would be no choice but to keep iterating until we got the right fit.<\/p>\n

This next point may seem obvious to a trained jeweler, but I was glad to learn firsthand that creating jewelry in a pliable cast metal such as raw brass<\/a>, bronze<\/a>, or\u00a0silver<\/a>\u00a0allows a\u00a0piece to bend into and out of place without a complicated closure. So these 3D printed hoops\u00a0are\u00a0a simple, hinge-free design, comfortable enough to wear everyday \u2014 and to sleep in without them getting tangled in your hair.<\/p>\n

\"Hoop<\/p>\n

 <\/p>\n

Step 1<\/h3>\n

We\u2019ll begin by creating a circle to establish the size of the hoop. I gave mine a 9-mm diameter, but you can make yours any size you like. Then mark the midpoint at the bottom of the circle to establish where our stopper bead will go. If you\u2019re using Rhino, I recommend using the Point <\/a>command.<\/p>\n

\"\"<\/p>\n

Step 2<\/h3>\n

Next we\u2019ll create the stopper bead by building a sphere at the midpoint we just drew. The size of the sphere is up to you; I gave mine a 3 mm diameter.<\/p>\n

\"\"<\/p>\n

Step 3<\/h3>\n

Then split the circle using the sphere as a cutting object. The resulting shape should resemble the yellow curve in the screenshot below.<\/p>\n

\"\"<\/p>\n

Step 4<\/h3>\n

Now we\u2019ll add some mass to our hoop. In Rhino, you can select the hoop curve and call the Pipe command to create a solid tube shape with a diameter of .8 mm. Make sure you select a rounded option for optimal comfort, since one end of the tube\u00a0will thread through the piercing. In Rhino this can be done by selecting Round from the Cap dropdown.<\/p>\n

\"\"<\/p>\n

Step 5<\/h3>\n

Next, we\u2019ll use our newly formed hoop to serve as the positive for carving a tiny notch into our stopper bead. In Rhino, we\u2019ll use BooleanDifference (other programs call this\u00a0Boolean Subtract) to cut the shape of the hoop out of the sphere, leaving a small indentation to hold the earring post in place.<\/p>\n

Once this is done, when you select the stopper bead you should be able to see the negative space for the earring post.<\/p>\n

\"\"<\/p>\n

Step 6<\/h3>\n

To make sure our hoop model doesn\u2019t fuse closed during printing, we\u2019ll have to move the stopper bead ever so slightly to either the right or left. For Shapeways brass, bronze, or silver, the clearance should be .4 mm, so I moved my stopper bead .5 mm to the left to be safe. (If you\u2019re planning to print your earrings in another material, make sure to consult the material guidelines<\/a> and design accordingly.)<\/p>\n

\"\"<\/p>\n

Step 7<\/h3>\n

Now we\u2019ll join the hoop to the stopper bead by selecting both objects and using the BooleanUnion command.<\/p>\n

\"\"<\/p>\n

Step 8<\/h3>\n

The final step is to create a mesh. I used Rhino\u2019s\u00a0default mesh settings, with the slider all the way over\u00a0to More Polygons.<\/p>\n

\"\"<\/p>\n
