This 52mm cap keeper and SD card holder base plate is designed speciffially to attach to the SmallRig L-Shape Grip for Nikon Z fc Camera 3480. The model attaches securly to the base and includes a slot for a spare SD card and has a cut out for a 52mm lens cap. It also helps with the grip on the SmallRig Grip by making the bottom flat where your fingers land.

Works with the SmallRig 3480 Z fc Grip. I believe it will also work with the SmallRig 3481 Leather Half Case for the Zfc but I haven't verrified that yet.
