Milk Bottle Lock for Tetra Pak

This is a remix of the Locking Cap from peaberry.
I have redesigned it to fit onto a tetra pak. With a nice knurled handle :)

You need:
* one M3-Nut (has to be inserted while printing the top part)
* one M3-Screw (cap head M3x6, M3x8 should fit)
* Adhesive (I used JB Weld)
* the original plastic cap that came with the tetra pak
* two nails (2mm thick)

Assembly Instructions:
1. insert the middle part in the lower part
2. screw the lower part and the top part together
3. make sure t
