Manual grinder that fits inside the Aeropress What is a good manual grinder that will fit inside of the Aeropress for travel purposes?

I'm looking for something as good as my Commandante grinder. I'm happy with the Commandante, but if I'm ever upgrading the grinder in the future I'd like something that will fit inside the Aeropress.
The Aergrind by Knock is made for just this purpose. No personal experience with this grinder, but from what I've seen it has good reviews: https://prima-coffee.com/equipment/knock/aergrind
