Funnily enough, when I told a friend I had bought a 3D printer, his first reaction was "What the hell are you going to use that for". Before I left his shop he had asked me if I could print a cup to fit in the drinks holder of his Jag, to keep coins in and a bracket for his powered wheelchair.

I have used the printer for all sorts, from cases for equipment to an alien plaque for a sculpture. I have printed a lithophane of my son and his new-born daughter.

What you can do with a 3D printer is limited by the build envelope of your machine and your imagination.
