Picture of Customizable 3D Printed Ring Designs
I designed and created 5 ring shapes and, in this Instructable, show you how to customize them in 123D. Even if you're like me and don't have a 3D printer, you can still customize your own ring shape and in a few clicks, send your design off to be printed. I've included all five designs for you to download and customize. There are STL files attached and links to the models pages in the 123D Gallery.

Step 1: The Files You'll Need

Picture of The Files You'll Need
Here are the rings and I've numbered them 1-5.  You can download the files here.  I've attached STL files and also included hyperlinks below so you can download straight into 123D and start customizing your ring right away!

I'll be using ring design #5 to show you how to personalize it with your initials.

hey everyone :) so i downloaded ring #5 and all the necessary software to put my initials on it but unfortunately 123D does not recognize the ring as a solid. This means that I can not SNAP, MODIFY, etc. The software always tells me to select a solid or a surface but I can not select the ring. Please help, thank you :)

these .stl files cannot be opened in 123D Design, so no use?

Hi, I love your work! Thanks for sharing it!
Can you confirm me that you got those rings shown in the photography above out of a Makerbot replicator 2 ?
And what is the superb material that you used to get that "translucent glass like look"

How do you get 123D to open STL files?

Do you have 3D printer? Which is cheapest printer for this? I am in India planning to buy one.

Hi chetancc,

I have a Makerbot replicator 2 but I have only had it for about 1 week. I am very impressed with its quality and it is very easy to use. It is not the cheapest one but I think it is a good balance between price and quality.

If you are not in a rush I would wait unit 2014. There are a number of 3D printing patents that are going to expire at the end of the year which will see a lot of new printers hitting the market which should mean they will drop in price. This is a short article about the patents - http://www.designboom.com/technology/3d-printing-patents-expiring-in-2014-will-see-market-erupt/.

I hope this is helpful.

Love it! It's my first time using 123D but it won't be my last. Thank you for showing a picture of every step not just a lot of text like some people do.
