The new line of Nerf guns come out recently and I've been upgrading my arsenal. I didn't have any of the clip style ones previously since I like having a place to put collected darts. I note the existence of an older “Flip Clip” accessory for Nerf guns which doesn't seem to be really available anymore. This is my answer to that allowing to use a clip style Nerf gun while still collecting used darts.Note that I'm using the “ring solid.stl” version. The other ones are included mostly for completeness and have not been printed. I'm not sure if this will fit with all Nerf blasters. It's pictured with a Stryfe.It's quite tight so that it holds the clips without adhesive. If it's too tight it wont allow the carriage in the clip to freely move and will jam. Don't push it up too high on the clips.
