@hmza27 I'm not the developer, but I do use this BoxPacker in our software.

  1. The dimensions are expected to be integer, not float.

  2. I also note that the inner and outer length of box 1 are the same, and inner and outer width of box 2 are the same, is this intentional?

  3. Just by checking the total overall volume, I don't see how they can fit in the small box.

Total volume of items: 4 * 203.2 * 203.2 * 12.7 + 2 * 304.8 * 381 * 76.2 = 19,795,573.312 Total volume of small box: 396.875 * 317.5 * 98.425 = 12,402,318.9453

19 (item volume) > 12 (box volume) so the items can't fit.
