A tentacle mini. I still can play easily with the original file. If you want the tentacles oriented differently I can do that pretty easily. Shoot me a message and Ill get to it.
I am still learning blender and havent figured out how to export .stl as proper size. Using cura I had to scale the mini up 2000%. I found that to be a good size. Obviously do whatever size you want.
I find giving it higher infill give it more heft and feels nicer, but low is fine to do as well.
