I was at my friend’s place and noticed the drawers on one of his cabinets. They were maple with dovetailed joints.
I looked it up online and found that you can buy replacement drawers quite easily. The size was just about right (15 x 11 1/2 x 4) for a controller. Of course you’d have to add your own internal frame/panels, but part of the woodworking is already done.
Im sure theres other sources for all kinds of replacement drawers, and as my research seems to indicate, they do custom sizings.
Just throwing it out there for you guys.
