co2 pneumatics for beetleweght robots

Your tank has a thinner wall than the one I turned down a tad. That was a tad under 5mm thick.

But for low pressure, 1.5mm should be enough.
On the other hand, with such a thin wall, any hickup or shatter when turning will give you less safety marge.
Do the hydrostatic pressure test please.
