Replacement cap for glass sport water bottle (stainless steel lid cover)

thingiverse

We have several of these water bottles but the plastic part of the bottle cap breaks easily if you screw it shut too hard. I created a new one that will almost perfectly replace the broken one and is even stronger. * First take apart the old lid. Remove the stainless steel outer cap, the silicone ring and the inner cap carefully. * Print the new cap. * Reassemble the cap the other way around. The inner stainless steel cap should be a tight fit. If the outer stainless steel cap does not fit perfectly use some hot glue or tape to broaden the diameter of the cap before you press down the steel cap. If the measure does not fit for you, I have included the OpenScad files so you can adjust the parameters and create your own modification. _Make sure you use a filament that is FDA approved or approved to come in contact with food._ I used HDGLass from FormFutura, which worked great.
