Here is a few pics of A hadron that I built a few years ago. I added an enclosure for the electronics board / rotary encoder / SD card board, added an enclosure for the power supply, added a heated bed, and a 3 spool wheel. I did a lot of cable tracks via Home depot springs. At the time, there were not allot of real reliable extruders on the market, so I had to make a spring loaded pinch clamp to make the printer reliable. I love the printer, rigid, accurate, and robust. I've also included a couple of pics of a 1/6 scale model engine I printed. The block includes water passages and oil galleys, and took 13 hours to print by itself. One of these days I'll get around to painting the rest of the parts.
