I've been trying to keep mine contained:
Putting the finishing touches on and filling a 2nd prototype (larger, of red oak, ebonized, solid brass hardware w/ corner protectors, dividers which didn't work out).
Next and hopefully final will have shorter arrow holder w/ concealed magnets, different handle on the centerline of the case, a mechanism to hold a plastic organizer in place.
Still not happy w/ the central compartment --- anyone know of a source for affordable closed cell foam? Or any other suggestions for improvements?
