Yeti Chug to Cirkul Cartridge
thingiverse
I decided to make an adapter that screws into my Yeti Chug and then you just screw on a Cirkul flavor cartridge. No need to purchase a Cirkul can/bottle or even a lid. It does require a TPU gasket (might be able to use PLA or similar but I didn't have any luck) to go at the bottom of the chug threads (see the picture). There are enough micro air holes in the print that it doesn't leak water but it allows air to enter the bottle after a swig of sweet, delicious flavoring. Enjoy!
