Milk Bottle Lock (UK)

thingiverse

I work in an environment where you could leave your money lying around and no-one will ever touch it, but food, and especially milk are regarded as 'fair game' by some. It isn't meant to resist determined efforts, but to discourage pilfering. This is designed to fit the standard molded plastic milk bottles in the UK which feature a 38-400 thread. I can't be certain about other countries. The lock I used is a combination luggage lock with a 3mm diameter shackle, but anything the same size or smaller will be fine. You can use the lid with a cable lock instead of the bar and pin if you prefer.
