rubber band boat (almost) remix

hello, will it is not as much of a remix. i did not change the design which works great (thanks for the designer) i just noticed that by chance or the designer knew about it that the square holes in the axe are the same size as the x lego black rod thingy (i dont know what its called) but i am sure if you have a lego set you know what i am talking about. so not to print one more part i put it in and it works perfectly ;) hehehehe.
