I liked the Sodastream Bottle Drip Snout shared by @Peter https://www.printables.com/fr/model/50222-sodastream-bottle-drip-snout
I printed it, but on first use, i didn't know where to put the bottle cap. So i added a “thing” to place the cap on it.
I printed it in PETG (Prusament Jet Black) with a 0.6 noozle.
The author remixed this model.
