MP-44 Optimus Prime Backpack Replacement Version 1

This is a replacement backpack piece for Masterpiece MP-44 Optimus Prime (Convoy). It is a simple part that uses the existing pins on the sound box upper flap and rotation point at the base of the spine. A first run plain box KO was used to test the replacement part. A earlier test print using Red Processed Versatile Plastic is shown so you can see how it matches the base MP-44 and KO MP-44 figures. I recommend using paint to achieve the proper red though. 

I used tools from a Watch Repair Kit to remove the pins. There are also Tutorials on pin removal for Transformers. Once the old backpack is removed, simply reuse the existing pins. Please note that the hinge holes on the replacement backpack are printed a little tighter than needed so you can adjust them yourself. This material is very easy to work with and requires little effort to sand for fitting.
