Vapor trap holder for mason jar
I made this "lid" for my large mason jars to hold my vapor traps as pictured. Here is the amazon link for the item https://www.amazon.com/QWORK-Vacuum-Bubbler-Borosilicate-Length/dp/B09VBHTQYX/ref=sr_1_4?crid=2HRDNJLZ6R90H&keywords=vapor+trap&qid=1701186363&sprefix=vapor+trap%2Caps%2C99&sr=8-4
One fit more snug than the other, but its tapered so the rim should hold it no matter the tolerance of the tube. Print with the large disc down of course.
