Autodesk's 123D Web app is an easy way to create 3D models that can then be sent to your 3D printer. For Valentine's Day, Autodesk has added a new app called Charmr that lets you convert a photograph into jewelry.
In essence, Charmr is a lot like those custom jewelry kiosks you used to find in Walmart. You upload a picture, place it onto the pendant or charm of your choice and then print it. What sets Charmr apart is that it generates a 3D printable file for you to make with your 3D printer.
For example, let's say somebody wasn't right in their right mind and wanted a charm with my face on it. With Charmr, I just simply have to upload the picture onto the sight, set it inside the charm of my choice and download the STL file.
If you don't have a 3D printer, you can still obtain a 3D print of your jewelry through Shapeways, Sculpteo and i.materialise. Shapeways may be your best bet as the company offers prints in a variety of materials that aren't plastic.
If you're like me and have a face that only a mother could tolerate, you might want to go with one of the designs already up on Charmr. At the moment, you can choose between some Milk Box earrings, a Ye heart pendant, a BFF pendant or a Year of the Horse pendant. There will be more designs added soon as more people make more charms.
