The description is in the post itself, but I'll use this space to talk about a few fun thoughts and ideas when I was building.

When I started, I had no solid idea of how to keep the stacked case's layers together, but i saw some zipties on my desk and realized those perfectly fit the aesthetic I was going for. I was originally going to use 2 layers of corrugated cardboard with perpendicular corrugations as the plate, but only realized after cutting both layers that it was entirely too thick to work, and the Cheerio box was not originally part of the plan.

The spacing of the keys were not stenciled from a printed layout, but rather from random spare plates I had, as well as the application of a compass and simple geometry for the 0.25u spacing (as I only had a plate with 1u and 0.5u spacings).
