The glass bottle capper creates a sealing, pop and snap cap for glass bottles. I recommend that you make the cap in a ventilated area/ window open and be careful with burning your hand. I suggest also that you make a “lip” that you can use to pop the bottle open easily and not make a sealed bottle that is hard to open. 

My 3d printer is the Creality Ender 3 V3 SE, and the capper was printed with Creality gray Hyper PLA. I would like to hear from your feedback and criticism to improve this invention!
