Nautilus Shell

thingiverse

This nautilus shell has two available .stl files, one with 1 mm thick walls and another with 1.5 mm thickness. The 1 mm version may not print well on a Cupcake MK5 printer, but should work better on an MK4 model. If you prefer the thinner walls, you can try printing it on a newer printer. The 1.5 mm .stl boasts wider internal wall configurations as seen in the second-to-last photo, which was adjusted to prevent walls from being too close together in smaller cells.
