This is a curled up version of the fabulous Friendly Articulated Slug by Isaiah.
I rotated each section of the slug in Blender using a printed curled up version as a reference. The uploaded model is about 314% compared to the original Isaiah's version (pi times bigger, pure coincidence).

Curled up version takes less place on a print bed, so now you can prin a really huge slug.
To this moment I didn't reach maximum size on a Prusa MK3, because it would take almost 4 days. The red one on the photo took about 2 days and weighs about 500 grams, so it's already a lot.

Hope someone would make something like 2 kg version that could comfortly sit on a person's neck!

A slug really benefits from using a translucent material, which makes it look slimier or sluggier I guess. So far I haven't tried PETG. Of course it prints well in PLA. Blue and red on the photo printed in SBS which I believe is only available in Russia or I simply don't know an appropriate brand name (styrene-butadiene block copolymer, SEBS?).

When you scale the model, brims could become to thick or too thin, so I recommend splitting the object into parts and scaling brims separately, or using your own brims (like thin cylinders in Prusa Slicer).
