13 ci HPA tank diameter?

[Rainmaker]

For the life of me, I can NOT find my 13 ci tank...
Could anyone take a measurement of the outside diameter of the tank for me? Preferably with a set of calipers.

Nominal 2" (slightly less) and falls into the "2" rule" for hydo on both of the bottles I have. Any of the 3.5, 4, 7, 9, 10 oz old school accessories work with them diameter wise.

here are some measurement using a Mitutoyo caliper at the base of the tank
measured at 68F

Pure energy : min 2.009" max 2.013"
Ninja : min 1.963" max 1.966"
Guardian : 1.980"

Last digit is not that acurate but that give you an idea

Thanks Grendel!
I've got a tank stock i want to print, but the diameter is coming out to 1.985", so I was curious how tight of a fit that was going to be.

Always happy to help, please post a picture of your print at the end, curious to see it!

Aren't the 3AL tanks still subject to the hydro testing rule and 3E tanks not?

Wish we still had the old forum, I went over this in high detail in several threads back there and really not wanting to do the research again to document it for the audience here again. All of the documents are publicly available and I recommend players who use HPA do their own research. The "2 inch rule" is an exception to an exception and applied to the two bottles I have (both Tippman branded). Each company who makes these stamp their bottle with the DOT/ISO exception they make them under so take the stamp information and look it up for the bottles you have and you will have your answer. That being said the filler of your bottle is the ultimate arbiter on whether they fill your bottle or not.

Sorry not being snippy, it is I have done the work to look this information up several time in the past and make long detailed posts with cited references and I no longer have the energy to do so again.

Here it is. Not my design, but it came out pretty good.

Nice!
PETG?

[Rainmaker]

Yeah, PETG
I was worried about stringing, but it turned out ok. Just a little inside the tank hole, easily cleaned up with a file
