Any idea where I can find a design for this?
Holy Cow! That is really cool! Most of that shouldn't be too hard to reverse engineer. I would like to see the locking mechanism that keeps it from launching and I would like to see how they do the seal. I'm wondering if they fill the inside with some type of sealant and let that dry before actually using the water? I don't think my prints could hold that much pressure without leaking if a sealant wasn't used???
