All credit to fuchsr for the remixed button tray and hybridtracer for their original designs.

This "remix" simply resizes the button tray from fuchsr to fit perfectly in the box alongside the original insert from hybridtracer instead of having the "misc" container as a separate piece. For those who have already download the buttons file, it just needs to be resized to 75mm wide x 124.4mm long in order to fit more snug with the original insert.
