This is a remix of DoggyDude4's Spinning Nerf Dart Tip.
I had to modify his tip to have a wider shaft to firmly fit into the body of the nerf darts.
I also did a modified version with just a shaped tip. This just fits in the Nerf Maverick Rev-6.
I've included the modified Spinning Nerf Dart Tip and the pointed version.
Also the shaft and base as separate STL files so you can build/modify for your own tip designs.
I removed the suction tips from the original nerf darts and used a hot glue gun to apply a little glue to hold the tips in the shaft.
