Articulated slug
thingiverse
I got inspired by the cute Slug thing #2818955 but I wanted to make a less visible joint. These joints are spherical so each piece can turn 360 degrees and move +-20 degrees. It prints out in one piece and can not be disassembled. There are two files to download. One with built in support and one without. My printer needed the support to print the eyes. The support takes a bit of careful cutting and sanding to remove. Also don't use brim or there will be a lot of work to remove it and free the joints. With 1,2mm shell thickness and 50% infill the slug is pretty solid and durable.
