@crashidaho_2052013 you have to use fusion 360 to adjust the size. There's a free hobby version for personal use (different than the free trial)
@crashidaho_2052013 I guess the boxes are not really designed to be that stretched. try to use the two hinged version without Stretching the clips. then they should not break as easy.
have done 3 - changed setting still unable to get the latch to work it just breaks off, but like the little boxes- i did stretch them to make bigger
