1.5l Milk carton lockable clamp

Edit: I added my first version of the model as well. It is a bit less detailed compared to the one I have uploaded earlier.

I got tired of colleagues "borrowing" milk from me so I decided to make a lock for my milk carton.

I had a few criterias for the lock that had to be fullfilled if I was to use this everyday.

-The lock should be easily transferable to a new milk carton once it the current carton is emptied

- No modification of the milk carton should be needed such as drilling hol
