i say thanks to my grandfather who helped me cut the pieces and lent the tools for the box.
i grabbed a smallish piece of scrap plywood and drew out what i wanted on the board

Step 3: Solving the puzzle

i put a nail in the top of the box.than put a nail on the table and set the nails in alternating directions. once i got to the end of the nail i set the last one on top of all the others facing the opposite direction of the second nail.once you have the nails placed correctly pick up the bottommost nail with your middle fingers and place the nails on top of the first in the box. if you dident understand my directions well enough i suggest looking through the pictures. if you have any comments, criticisms, or questions please leave them in the comments or pm me.
