Installation Instructions

Follow the guide below to properly install your upgrade LCD extension kit for proper fit and function:

Next up is the monitor extension PCB! Use two small strips of 3M VHB mounting tape and stick them on the back of the PCB. You can use any other strong double sided acrylic foam-based tape that is about 0.5mm thick.
Align the monitor extension PCB with the back of the LCD and stick it down and connect all the plugs. NOTE the above image is the new version of the LCD case which uses 1mm carbon fiber side plates to secure the connector plug in place to prevent stress on the LCD when mating the connectors.

If you have the Pigeon 3.0 cage LCD case you will need to 3D print a TPU brace that slides and clicks around the connector and provides support for the plug. You can find the STL for that HERE. Download the "PCB Brace V5" part file.

After 3D printing your PCB brace you must use side cutters to trim off the bridging filament that supports the latching clip so that you can fully insert the brace and latch it into place behind the connector edge to lock it.

After adhering the the monitor extension PCB to the back of the LCD and connecting the ribbon connectors, slide the TPU PCB brace onto the connector until the internal latch engages and clicks into place. You may not hear a click since it is TPU, but you can tell visually when the bump is gone and the surface is flat.
