This script will put the results in a file called results.txt in the same folder as the script. First get the Mint Address of the NFT which you can often find in the URL of NFT Marketplaces when looking at the details of an NFT for instance https://coralcube.io/detail/61hPLmqccP6Gx8xQz8ekZh5Wun2FAnwRbzvs5ucxmXHm and the Mint Address is "61hPLmqccP6Gx8xQz8ekZh5Wun2FAnwRbzvs5ucxmXHm". Once you have that put it into a Solana Blockchain explorer like https://solscan.io/ and you will get to this page https://solscan.io/token/61hPLmqccP6Gx8xQz8ekZh5Wun2FAnwRbzvs5ucxmXHm go to the "Metadata" page and scroll down in the Metadata to where it says "creators" and there is an array. Take the address from creator array key [0] which is "6LQgfAN3LQMHKHQFUpMsCCQnPrnMAH46yQvt85vYTUb4", this is also known as the Candy Machine ID generally for Metaplex. Then use the function metaplex.nfts().findAllByCreator() from here https://github.com/metaplex-foundation/js but as of now ensure to use it with an RPC that is capable of processing it. As of now 11/1/22 I know Quicknode works with it but Alchemy has an issue and didn't give results when I tried with it. Here is a code example, in the below code example edit the "rpc" variable to be the URL of your RPC provider and edit the "creator_0_key" address:
// Mystopians root.data.creators[0].address 6LQgfAN3LQMHKHQFUpMsCCQnPrnMAH46yQvt85vYTUb4
// npm install bs58 bip39 ed25519-hd-key @solana/web3.js @metaplex-foundation/js
var rpc = "---edit---";
var creator_0_key = "6LQgfAN3LQMHKHQFUpMsCCQnPrnMAH46yQvt85vYTUb4";
