At long last, I was able to make one.
Its 1/4 scale, that's approximately the size of the matrix in your hand- if your'e Optimus Prime.
Very strong material. You can actually stab it in your chest and kill yourself.

Tech Specs:
-modeled in Rhino/Solidworks
-bronze infused stainless steel 3d print
-13cm length (approx 1/4 size of original)
-single piece construction
Forgive the photos. Im so excited to post, I didn't take time to make a decent setup. I'll upload the hopefully better ones later.
