7 dart cylinder for Nerf Hammershot. Was originally going to be a work in progress due to initially missing rotations a few times but after a couple dozen cocks everything seemed to settle and now it never jams. Including Solidworks files as well. Make sure to remove the stock air restrictor.
EDIT: Now includes a cylinder that fits FVJ darts better, a spinner with a looser fit, and a peg that fits the Sweet Revenge better.
Spinner seems generally fine at 20% infill for most printers but may require higher.
Joining Cylinder and Spinner Post
Softly hammer spinner post into back of cylinder until surfaces are flush with one another. Graphite lubricate helps but is not needed.
