I thought this exact same thing recently, but noticed that the middle foam layer may not be tall enough:
FOAM LAYERS:
Layer 1 (Lid): 1.38" - Convolute
Layer 2 (Base): 0.50" - Pad
Layer 3 (Base): 3.38" - Pick N Pluck
I’m interested to see if Norns, oriented vertically will fit. It looks like there’s not quite enough room in the Pick N Pluck layer to fit Norns without relying on the other foam layers (base & lid).
