Just printed one and tried it on several different Mason, Ball and Kerr jars - unfortunately, it does not fit any of them very well = (

OK. Thanks again for letting me know. I updated the model with one that is 1mm narrower diameter which allows it to screw down more tightly but is still loose enough to screw on and off easily. Insider diameter across the tops of the threads should be 69mm.

Is it too big? Too small? We have used it on both Ball and Kerr brand small mouth jars without any problems. It is loose when it first goes on but screws down tight.

Slightly too big and when I tighten down it pops out and is loose again.

Did you have supports on in the middle? Maybe residual supports got in the thread... I only supported the outside when I printed it.

No - only did supports on the outside.

Thanks for the comment. I think you may be right. I just mic'd mine and it printed with 69.3mm inside diameter across the tops of the threads. I drew to to be 70 so looks like my printer is a bit out of cal. Do you have a mic and can make the same measurement? I probably should reduce the insider diameter ~0.7mm. Meanwhile, you could try scaling just the X&Y by 0.99.

okay - using calipers and measuring around the circle across the top of the threads, I get measurements between 69.7mm and 70.2mm.
I don't have the ability to measure depth of threads.

Thanks. I think it needed to be closer to 69mm. As you can see in my pictures my old printer was over-extruding which led me to widen it to 70. Model has been updated. Sorry for the wasted time&filament.

Think I will do a print of just the thread portion before doing a full reprint - we really like the model.
Question - any chance to make a mason jar type with the 2 eyes minion as well? Your remix says it is for a different type of jar.
Thank you.

Yeah, that one is. I just made a new version with with Ball/Kerr small mouth jar thread and added it to this this. Enjoy!
