This Friendly Articulated Snail is a remix of thing:4847937 by Nebetbastet which is actually a remix of Isaiah's Slug. This version just has the protrusion to allow the snail shell to attach.
This blender remix allows easy printing with default settings by adding a simple brim that connects all the parts on the bottom and just peels off once you finish printing.
See original from thingiverse for more photos and base models.
This is very similar to thing:4906051 that I've printed at 0.4 and 0.25 on a Prusa MK3S+. If you aren't confident in your printer setup I suggest going with a small nozzle.
The author remixed this model.
