Seriously. Put everything you own in a custom cutout foam block. Tools, desk supplies, microphones, animals, canned foods, whatever. It’s unnecessary, time consuming, spatially inefficient, but dummy satisfying. It took me a couple tries to get a clean cut, but if you’ve ever messed with the precut squares, you know the problem of those collapsing. I recommend a nice Xacto knife, tracing a 1/2” deep slight angle inward, then pulling and cutting. Your OCD will love it.
