otf box

a remix from https://www.printables.com/model/664268-no-rubber-band-fully-printable-otf-fidget-toy

i remixed it to make an otf box.

i replaced the blade with a box.

 i changed the spring end to be better at holding box/blade. and made it wider

i increased the height of the side spring

i made the cover to clip on and hold together better.

i made a square hole in the main spring  to make it strong. the original is to weak.

changed the spring design.

other changes also.
