I have two bound drafts of my first novel, plus the hand-written one, and in a few months, it will exist as a real book. There's something magical about being able to hold physical copies of its life cycle. You can feel all the weight of the work you've put into it over the years. It's tangible. Of course, the first hand-written draft is hugely different from its final form, and a lot of that development I was able to do with pen on paper.
That's not the only way to keep analog in your life while you're eyebrow-deep in edits. Edits require lots of Keeping Track of Things. Lots of planning. Reminders and restructuring and outlines. Deadlines to schedule, lists of people who have been helpful. Lists and lists and lists. I keep what I call a "brain book" (or sometimes several) for every project where I can track all of this information. In the last few years I've been using the Bullet Journal method to help tame the chaos of these notes. That brain book becomes like a book planner--and it, too, makes a nice keepsake of the process of a big project. It's fun, and a little daunting, to flip back through those notes and see all the work that went into the book.
