Vase Mode Rifled Nerf Blowgun

thingiverse

I've made two significant upgrades to the rifling models: one with a 165mm tube height and another with a 335mm tube featuring a mouthpiece for those who require larger build volumes. My tests have shown that this new design yields better performance. When building a Nerf blowgun, it's essential to do it right. I've created a simple model designed specifically for Nerf Accustrike type darts (.5in). It's crucial to print this in vase mode, as printing normally will result in a solid twisted rod. The settings include zero bottom and top layers; however, a raft may be necessary depending on your printer. There are two models available: one is designed for high build volume printers with a mouth cone at 270mm in height, while the other has been shortened down to 160mm in height. The rifling design works effectively, as evident from the spinning fishtail observed when blowing air into it. Although the darts may not be spinning extremely fast, the effect is noticeable. The design utilizes pentagonal rifling due to its ability to provide a better fit on the dart with reduced blowby. The ratio of 1 turn every 100mm has been implemented for optimal results. To achieve the best experience, it's recommended to use natural color filament. I've printed several models in natural PETG, and the outcome is impressive.
