Cut, butt, back fully. Planes have happily lived in fully enclosed
toolchests for literally centuries.

What concerns me is that you've got something more suited at 3" to mount on
a wall rather than stand up. My under wing shelf (8") gets bumped once in
a while, which makes me glad that it holds only unbreakable.

I'm knocking out a little set of shelves to go under one wing of my TS and
hold my collection of hand planes close to my workbench.

I had one odd piece of plywood salvaged from a library magazine rack, and
I
more or less just started cutting on it without a concrete plan. I made
the first crosscut as wide of a piece as I could manage in my little shop;
somewhere in the neighborhood of 30". I cut the next one to the same
length. That left me with a third piece a smidge longer than the first
two. I ripped it into four equal pieces 3" wide. I chose to use narrow
uprights to encourage air circulation, to keep the rust off my planes.
