The file 'Shotgun Slug Remix 3D Printer Model' is (stl,blend) file type, size is 1.5MB.
Both versions have a channel for improved spiraling, and V2 has improved aerodynamic performance. Both have a lengthened payload area for higher mass.
Both are designed to fit M5 20mm bolts.
This remix was kind of rushed, so I included the blender file for others to tweak the curve, channeling, etc, of the slugs.
