Milk Bottle Lock (UK) FOOD SAFE

thingiverse

Excellent work by naskinner on the original of this. I was uncomfortable with the idea of milk being in contact with my PLA so I simply remixed the lid to press fit a UK bottle lid. (should work on most.) Its tight enough that you can swap it out but cannot be removed easily once locked down. The rest of the files are still at the source thing which deserves the credit here.
