Edit Note: Added BodyKun and some minor tweaks (25 Apr 2020)
This rig was made because of me having no money to buy a drawing figure so I decided to make one myself. Even though I only did this for the purpose of having some sort of pose model to draw off of, the rigging process was done pretty neatly using Rigify add-on. I believe you can use the rig for your mechanics shots if you will. I'll update more on this one once in awhile, so please stay tuned for the time being. Cheers!
