It’s a set-top box that can drive print operations on attached devices. It’s like a print server for 3D printers. Usage is straightforward: GCODE files generated by slicing software are “printed” to the 3DPrintBox via ethernet or WiFi. The GCODE is stored on the 3DPrintBox, freeing up your desktop or laptop for other use.
German RepRap will be offering the design to the open source community.

It’s @OctoPrint ! In a box!
Does it come in an optional LEGO compatible case like the 'Pi? 
At that price I’d expect it to visually detect jams/clogs/fallen supports and stop the print too.
I’d like to know the power of the processor, but I doubt this adds anything a raspberry pi B+ in a 3D printed case can’t do!
+Mark Rehorst just use a raspberry pi to free up the laptop. If your printer is in a different room or on a different floor then remote monitoring is much more useful!
Three printers on one box is cool, but I only see three USB ports. So, maybe they should have said “three printers OR webcams”.
I’m sticking with OctoPrint for the foreseeable future.
@Mark_Rehorst You are right. Only good for printer farms but still you need somebody taking care of the machines on-site…so I see no big benefit for home usage.
