How to make your first 3d Printed Round Open Cuff Bracelet!

Featured
This is a relatively straight forward instructable on how you can make your first 3d printed round open cuff bracelet and print it on your home 3d printer or through a service such as Ponoko, i.materialise, Kraftwurx or Shapeways. I will be 3d printing on my Afinia H-Series 3d Printer.

You should also have a basic understanding of 3d modeling but I will be walking you through my process The concepts and techniques are not difficult to understand. You can also use any modeling software such as 3ds Max, Maya, or free alternatives such as Blender, Sketchup, Autodesk 123d, and any other programs of your choosing. I will personally be using 3ds Max.

You'll also want a few measuring tools such as digital calipers and a fabric tape measure. The calipers will help you accurately measure in mm for 3d printing and the fabric tape measure can measure the length of your wrist. You'll need to convert those measurements (inches/cm) to mm. You'll always be measuring when designing for 3d print!

Step 1: The Design

Even if you just want to make something that is super easy in theory, a lot can go wrong. It's important to know the size and dimensions of whatever you're planning to make. If you're going to 3d print at home, then you'll be limited by the size your 3d printer can print at. Helpful tools would be Digital Calipers, Rulers and a fabric tape measure. 

To start, you'll want to measure the width of your wrist. The cuff that I will be showing you how to make is a rounded cuff so the measurements won't have to be form fitting since a round shape is easy to get on the wrist. If you want to make a round open cuff bracelet that is more fitting to the wrist, then also measure the thickness of your wrist as well. Write down the measurements somewhere and keep it for reference later. You'll also want to have sketched out a basic design you would like or found some reference pictures of cuffs you like. Having some sort of blueprint on hand is important to keep you on track, even if you don't follow it entirely and just use it as a loose reference. It doesn't have to look that great either (see my example!).

Depending on where or how you will be 3d printing your round open cuff bracelet, minimum wall thickness will be an issue. Shapeways explains this thoroughly, I encourage you to read it. Also, to print in different materials like metal or ceramic, your model will need to meet the minimum thickness requirement. i.e. Shapeways can print in Stainless Steel as long as your model has a minimum wall thickness of 3mm. Also, the amount of detail in your final 3d printed piece is also limited by the materials minimum detail measurement so be sure to check with the 3d printing service that you choose for the exact specifications so that you can create your model with those things in mind. It will save you a headache later on and you won't get your model rejected from their service for not meeting the minimum printing requirements.

This is awesome. I really want to make one. But it seems a little difficult for me.

You don't know unless you try! Even then, nothing is easy in the beginning, you only get better with practice, especially when it comes to 3d modeling.
This looks great! I've been wanting to try to make 3D Printed jewelry sometime :D
Thanks! It's my first Instructable so if you have any questions, just ask! :)
