The displays from Ambient Weather have a keyhole mount, but those holes do not align with the 40mm IKEA SKADIS pegboards. This small adapter will accept two M3 screws and had hooks that neatly fit into the pegboard.
This was designed for the display with my WS-2902D kit, but I think it will work with other models. The spacing between the keyholes was 73.5mm.
The hooks were taken from DavidsGotWood's Ultimount. I sunk his hooks into my model for a flush fit, allowing you to print the file in one piece without supports. I would print with a brim to ensure good bed adhesion.
