So as to avoid being labelled as a Commodore FanBoi, I decided to release a classic Atari machine, the 520ST; and not just that, mind you, but also the SF354 disk drive and SM124 monitor. Perhaps Atari's greatest machine, and amazing when you consider it was built only from off-the-shelf parts, and designed in a couple of months.

Pretty straightforward build, use the photos for guidance. The only hint is to add the screen decal to monitor_back.stl first, and then slide/glue monitor_face.stl over it.
