Kệ treo tường bắt vít (Wall Shelf)

i made this model to screw into my wall for when im working in the barn and want to take off watches, rings, glasses, and anything else smaller. it has holes sized for drywall screws. this model isnt finished and i will most likely add hooks or different additions, this model is made big on purpose and is supposed to me cut in half using a dovetail cut to best line it up when being glued. please add comments on what i can change and be better about. i have not yet printed this is still a draft.
