I use a lot of different nerf shell types in my foam flinging and didn't want to have to change my gear for each unique shell type so I came up with universal holder which will hold pretty much anything depending on how much you adjust the elastic. Took a lot of inspiration from Zach Freedman's warp saya design.
The author remixed this model.
utilized the two separate molle pieces to make it easier to print the universal holders and added a slope to the molle stick to make it easier to assemble
