Mason Jar lid with threaded hole or not

thingiverse

I attended a baseball game over the weekend and picked up a mixed drink, which was served in a plastic mason jar (as seen in the picture). To avoid spilling my drink, I decided to find a lid so I could set it down without worrying about a mess, but trying to figure out the thread proved frustrating, giving me a headache. Luckily, the print settings allowed for five prints, which can also be used as parts trays. After the first one failed, I thought, why not add a straw hole? Then, I wondered if making an internal straw would work, and finally, I decided to do both so that the hole is threaded (the two-part straws are currently printing). If printed on glass, it could have come out with a more polished finish. However, I had ironing turned on, which may not have been ideal. With only 5% infill at 0.8mm (2 walls), the part won't be watertight since it has a hole, so I didn't need to worry about that. An added bonus is that the reduced infill also limits the cold from the drink to my hand. As an additional experiment, I quickly printed two mods: one without a hole and the other with the hole on the opposite side. These will be useful for printing another part at a later time so that the team logo can face outwards. It's unclear if this design is unique to our ballpark or if it's done at other stadiums. The design may not fit glass mason jars since I don't have any to test with, but the opening on the plastic jar I used is 70mm. The dimensions of this design are 78Øx26mm, and the straws are 10mmØx10 and 100mm. The threads are standard metric at 10mmX1.5. If necessary, you can scale up or down on the Z-axis for the straw, but hopefully, the threads will still work. Clearly, this design is not dishwasher safe.
