Interested in a 1507 Air. Custom colors don’t interest me that much, but if there’s any chance of group buying some kind of more keyboard-oriented foam insert, that would definitively interest me. Having used pick and pluck foam numerous times for camera equipment, I’ve found that heavy equipment can cause thin areas of foam to tear away from the rest of the block if the case isn’t completely full, like an ultratelephoto lens....or a heavily weighted keyboard that you put your heart and soul into building. I could easily see a keyboard doing this if other sections were left empty.
Idk if there is any kind of one size fits all solution that would be better for keyboards than the general pick and pluck because of the variability in board dimensions, but I’d probably toss the original foam in favor of custom cutting an insert myself out of a large block of sturdier foam.
