Nikon used to supply them with their cameras, my first Nikon, a D90 had one. Then Nikon got too tight a***d to supply them, just like their lens hoods...I bought 5 in a bag from Wish.com for $5...Nikon wanted AUD$20 for one.
The Wish ones even had a spirit level in them..never used it but it's there if ever I do..they are also rubber and slide in a grip very well.
Come to think of it my old D90 had one too. I gave it to a school photography class with the cover attached.
