Funnel Collar for easy bottle filling

thingiverse

Using a funnel to fill a bottle with liquid is a two-handed job. When the funnel sits in the neck of the bottle, the air cannot escape as the liquid is poured in and so the flow into the bottle is very slow, or you need to lift the funnel periodically to allow the air to escape. This collar sits on the top of the bottle and the funnel slots into the top of the collar. The holes in the wall of the collar allow the air to escape while pouring in the liquid, making it much simpler to fill a bottle and keep an eye on the liquid level in the bottle. The size of this model will fit most spirit bottles. You can easily increase or decrease the size using the scale function in the slicer if necessary.
