Pure Leaf Tea Cap Insert with Straw hole

thingiverse

Little background. My girlfriend has CP (cerebral palsy) and has some trouble holding on to some things or even taking caps on and off of pop or water bottles. So, She likes to use a Straw so she don't have to keep unscrewing the cap. Now, With this being said. She bought a bunch of 1 pint Pure leaf tea bottles. And bought some Reusable Stainless Steel Straws. So i decided to Design a Bottle "Insert" plug if you will, it will go on the inside of the bottom and push down, then you insert the straw, that way nothing can get into the bottle, and she'll be able to pull out and transfer to another bottle once she's finished with this one by just pulling out and inserting into the next bottle. So I hope this can be of use to others that enjoy using a Straw to help keep bugs out of the bottle as well as make it easier. Middle Hole is 7mm so should fit just bout any Straw, metal or plastic or even paper. The outer diameter that inserts into the bottle opening is 30.50mm with a lip on it so you can pull out easy and put in new bottle. I've been trying all day to get the threads right for a screw on lid but can't seem to get them right, so got frustrated and scrapped the project for now or put on the back burner, got tired of wasting filament printing it out to try and get it fitted correctly.
