This RepRap has been a work-in-progress for quite a while.
Current Status: in late 2015, it did print something that actually resembled an object.
In mid-2016 it again printed something that resembled what it was supposed to. And then promptly didn't after that one (extruder clogged?)
Next plan: maybe get some extruder cleaning filament, and try printing again with filament that isn't five years old…
To use: This RepRap requires a USB connection to a computer.
The Raspberry Pi in the printed case near it has Octoprint installed. When it's running and connected to the MakerNet network, you can access that at octoprint.local.
