Very cool! Is this posted somewhere? I’d like to remix/throw you some updoot. I guess dm me link? Not sure on the rules about that.

I also made a filter container once, mine was for wall-mounting. It was a great thing to have, so I think you will really like it as well :)

Looks good! Is the white thing a door that closes, or just a support?

One thing I do with my filters is to flip every other one upside down because they like to stick together. This is a favor to pre-caffinated me. So as nice as your design is, I would have to modify it.
