My fancy magnifying glass spring arm lamp broke. The stem connecting the head to the neck snapped in half where the bolt attaches it to the neck. It was either trash my lamp or fix it. With 3D printing now becoming available I couldn't help but to try it out for fixing my lamp. At first I wanted to print it in steel, but that proved ridiculously expensive so I settled for the nylon plastic. Just a little while with blender open on the computer and a caliper and i had a perfect copy model.
It took a few weeks to get back as I ordered it on Christmas, but the results are impressive to say the least. Its a perfect match for the old one, the print was extremely accurate. In this picture its a little dirty and scratched but that's just because I had put it in the lamp and taken it back out already. I sent it to Ponoko to be made. For only 19.93 which is pretty good for what is essentially a custom prototype part.
And here's a picture of it in action:
