My esteemed listmates, I found a mason jar lid on Thngiverse. https://www.thingiverse.com/thing:3468220 A patron needs these specs Top of lid: i ¾ inches O.D. Bottom of lid: 113/16 inches O.D. Depth of lid: 9/16 inches But, Tinkercad doesn't measure in inches and I'm not even sure Timkercads could achieve that kind of specificity? Meshmixer is an amazing prgmnra that I haven't mastered yet. What free program would you use to create this with such detail? Thank you, Charles.
