510 connection measurements

[njvap]

Guys, has any one taken the time to have the 510 thread on paper I mean tge measurements so it can be machine cut?, there are countries where corruption is so high that vaping is exclusive for high class, I want to help solve this problem

I wouldn't be surprised if some of the numbers in 510 dictate measurements. Like 18-650

Also, wouldn't be surprised if they didn't.

510 = 7mm x .5
