This is a screen mount that fits onto the side of my SeeMeCNC Rostock Max V2. The side is covered by a blank on new printers. I removed the balnk and placed this screen mount in its place.
It can also replace the LCD on the front of the printer.
The screen is a 7" LCD with a SSD1960 controller. Any cheap model from eBay will fit as they all appear to be the same part. I got mine from Amazon in the US.
I no longer have a Raspberry Pi running OctoPrint inside the base of my printer.
I recently upgraded to a Duet WiFi with a PanelDue and this is now the only screen mounted on the printer.
FYI: The green parts are "Rostock Max V2 - Triple Strong Bed Clamp - No hardware needed!" by Artesian and can be found HERE
