I was intrigued by the whole concept of the Raspberry Pi. Had not heard about a fully functional microcomputer for so little money before this. I'm usually focused on computers on the other end of the spectrum, huge behemoths with multi-cpus, multi-gpus, etc. So using one sounds like a fun tech project with the benefit of being able to remotely send the printer files. The thought of saving to an SD card and taking that back and forth from the computer to the printer sounds a bit old school. Most likely I will have the printer in a remote room so being able to check on it with a remote camera or web interface will also be convenient.
Very cool reindeer print. I'd be interested to see pics of the progression from 3D print to final painted ornament.
