I used to work in aircraft maintenance on F-15s. We'd have entire toolboxes with cutouts, just like the example.
I still use a "physical" checklist as I get ready in the morning - my wallet, keys, ear buds, and keys all have their physical spot over night and in my pocket.
Oh, aviation is known to be one of the most profound checklists' users. It's interesting to also learn that the specially designed toolboxes are also in wide use. Thank you for sharing!
Yeah, what a big pleasure to keep the head unloaded because of the order of the organized space.:)
