Sodastream Glass Bottle Anti-Blow Out Preventer

thingiverse

made this adapter to help prevent blow-outs while filling the threaded glass bottles, on my penguin style filler. it seems it was made for the hex style glass bottles, rather than the threaded ones, so quite often when using the threaded ones, it buckles the seal and explodes the water/co2 all over. since using this ring on the threaded bottles, it hasn't exploded/buckled once. the cap should be even with the top of the glass bottle, as it is just for adding extra support, and not for creating an air-tight seal. when using, the thick part goes towards the base of the glass bottle, or the thin side goes upwards, towards the seal.
