so I am building a stand with a 3D program and I want to have a few tanks fit on this. What is the exact diameter of a 510 connection on tanks. I need it to sit flush. I cannot find my tool to find the diameter of it. If anyone knows please let me know.

510 Threading is 7mm x .5mm

7mm Diameter
0.5mm Thread Pitch
A 7 mm circle will be able to fit the 510 in to my stand. I don't want to screw it in just needs to sit in there.

Yes, a 7mm circle (3.5mm radius) should hold all RDAs and Tanks with 510 threads, although I would probably ream out the holes just a tad, so the threads won't bite against the holes. If the hole is the exact same size as the threads, it might still want to try and thread itself in, so reaming the holes out to about 7.1mm should have them sit nicely, without threads biting, or without tanks tipping and sitting offset.

Sweet thank you so much. Hopefully as soon as I finish this stand I can get it printed to see how everything is. I'll post photos eventually of the boxes and the stands I'm making

I'll be waiting patiently to see the results :)
