Soap holder with locked filler - smaller length, lower filler

I like the original desing, especially the filler lock, but for my soapes the box was too large (length), so I modified it a bit: I reduced the length of the box to 110mm and the filler was changed accordingly. I placed the filler even lower (4mm from the inner bottom of the box) and I reduced the thickness of the filler to 3mm (enough for my requirements) The bottom of my box is without the non-skip tread of the original design
