About this model

This is a 12" rocket that slides over the barrel of my air cannon. My barrel is 2" ABS pipe, which has an OD of 2.39", and the rocket's ID is 2.45", so it fits nice and snug without binding. Fair warning, it goes a lot farther than you'd expect. If this is your first time shooting your air cannon, make sure you have a LOT of room, probably two or three times what you think you need. At 75 PSI it'll go way up if you shoot it straight up, or a really long way if you aim it out toward the horizon.Since it's 12" tall, it prints standing up in one piece on the Bambu H2D and other printers that size. I print mine with 2 walls, 10% infill, and a 5mm brim. It can get beat up pretty easily depending on where it lands, but I'd rather have the distance than make it tougher and heavier. I'm also work…
