You may call him a tardigrade, but he is actually a Water Bear.
The arms are designed to not need supports, but I used organic supports on his chin and snorkel. The project file (.3mf) shows the painted-on supports.
The author remixed this model.
Severed the moss piglet head, added the head of a water bear. Merged the two to create the most realistic Water Bear STL file available on the internet.
