Yubikey 5 Nano Cover for keyring thread

I have a Yubikey 5 Nano that I like to keep attached to my keychain. To protect the USB contacts, I used the awesome cover made by FoxAmes.

Unfortunately I am the kind of guy who looses little things like this cover, so I added a hole for the keyring thread so that the cover is attached to my keyring and cannot be lost.

This has the added benefit that the loose thread is a bit shorter while the Yubikey is inside the cover and a bit longer when I plug it in my computer.
