Picture of Litho Lamp
I'm getting married in a few months and like most wedding couples we want a way to display our personalities and save a few bux.  Our rehearsal dinner is going to take place in a park from 6-10pm.  This presented the problem of poor lighting.   Having seen MakerBot's awesome lithograph customizer, I had an idea for a lamp.  Well....about a dozen lamps.  

We also live in Indiana and are getting married in Colorado.  Needing ten to twelve lamps also means that shipping completed 106mmlamps would be cost prohibitive.  I need these lamp to be flat-packable and capable of being rapidly assembled.  I also need the light to last for 4-5 hours.  The LED will draw ~200mA, so two AAA batteries will power it @3V for about 5 hours.  I had originally wanted to use coin cell batteries, but they wouldn't last long with this powerful diode.  Once I knew what parts I would be using, it was time to design.

How is 3D printing so expensive? Is there no cheaper way to make something like this. There is no way one picture should cost 40 bucks. Am I doing something wrong?

the equipment itself is really expensive. but if you buy like a reprap (about $700 for a kit) it will only cost you for the plastic which is about $13 for a pound of plastic.

another reason might be the company uses the method where they put down material dust and melt it with a laser. (really expensive machine and really expensive dust)

Fun! I love when 3D Printing and photography is mixed!

Hey, thanks. I liked that I could design something unique enough and cheap enough to help with our wedding. This project really helped justify some of the cost of the printer. The rehearsal dinner that these are for are tonight and I hope to be able to post a picture of all 10 lamps in action before too long.
Purple is my favorite color and this lamp just looks awesome :). Thank you for sharing your awesomeness :).

I forgot to include..... Our wedding color is purple. Hence the purple and the further customization of the wedding.
