2 liter PET Bottle Bottom Stabilizer for Willy's Eldorado Kolsyrad vatten

This is for 2 liter PET bottles with a diameter of 100mm. Tested on and designed for Willy's Eldorado Kolsyrat vatten bottles here in Sweden, but may work for other bottles. Our bottles have a small lip at about 48mm up from the bottom and the model has little “claws” to grab over that lip. Additionally you can print a lock/tightening ring to slip over the main part if you want more tension to hold the stabilizer in place.

What is this for?

We reuse our 2 liter bottles a lot as drinking bottles but they always get their bottom dented eventually and then they tend to fall over since they're not sitting straight anymore. Unsurprisingly this is a very niche problem and I could not find an existing solution to this so I made this.

Print settings

I printed this in PLA without supports on an Ender 3 v2 and it worked fine except for some stringing between the towers. It may work better in PETG due to it being less brittle but I don't have any of that here to test that.
