I've found plenty of generic onion vanity generators, but somehow the files created aren't useable by bitcoind. It's probably a minor tweak needed, but I've not managed to work out how to do it yet. Has anyone?

v2 address no longer supported by Bitcoin Core (and most updated software which use Tor). Meanwhile v3 address for his node isn't vanity onion address. Even so, he might know how to do it, but don't bother configure his node to use vanity v3 onion address.
Thanks I was not aware of this change thanks for the heads up
