Here are a few bone shapes for your rig.

Wow this will save me a lot work for my next project, Thanks a lot. :)
This is a really cool idea. I'm still kinda new to blender but not super new. I know little to nothing about rigging, only bones. How do you put these on the rig? do you like create a bone in the mesh and apply one of these to the bone?
Great, Thanks!
