Welding tank hook (remix)

I LOVED the hook design by VojtaFox, but when I made it I realized it didn't easily fit any of my gas bottles. It said it was for "10 l old pressure vessel," and needed a lathe-turned additional piece. So I sized up the hoop and now it just rests over the top of my bottles (fits my 80, 150, and 244 cu ft bottles). It's not a perfect fit, and can slide a little, but it should do the trick. If anyone wants to tinker around to perfect it, I'd love to see it. I just don't have the time for it. I was also worried that sitting out in the cold shop it would become brittle and break, so I scaled up the thickness and added a bit more material to the junctions. Finally, I re-oriented the printing position of the legs so the longer "grain" structure of the filament runs along the least-supported part of the leg, and the weaker grain structure is where it is under compression resting against the tank. Hopefully that will add a little extra durability. Maybe.
