Spiralized Cylinder for the Nerf Hammershot 8-shot Mod

These parts are designed to use a few solid layers on the bottom and then a continuous and unbroken profile all the way up the part. Prusa and Slic3r call this vase mode, while Cura calls it spiralize. I prefer Cura myself, since Slic3r gets a little persnickety about the bottom layers.

Thanks to Tyrant for pointing this out: For users of Prusa or Slic3r, they don't seem to appreciate the 0.05mm gap separating the lower half of the cylinders on the default 'Slice gap closing radius' setting. Th
