This is a foam dart holder I made a while back before I even had a 3d printer. I really like this because you can keep your bullets in it without ruining them. I recomend you print it upright with supports because if you print it on its side the supports are super hard to get off and it will the scratch bullets. If this is poular I will try to make a quicker printing and no support foam dart holder. I will also look into to making nerf gun holders too. I created a lid although I really didn't need one. I printed mine at .2 mm layer height on the Creality cr-10 mini.
