Milk & More Bottle Top (Lid)

A basic milk bottle top for milk bottle such as the ones delivered by Milk & More.
I started with a very tight fit which was leak-proof but it's to difficult to get off and hence I relaxed it a bit.
This one will still stop spillage if the bottle falls over but if its upside down/on its side for a while some milk will leak.

As rightfully pointed out by applebomb511: "PLA is food safe but due to the ripples/layers it leaves ALOT of room for bacteria so make sure you clean it GOOD!"
