Here are some parts from my Diaclone themed MP-10 add-on kit. the full kit includes extended antennas, Shoulder Rockets and Sword to date. Extended Smokestacks to follow Enjoy DS
Nice work, never knew the diaclone didn't have the silver stripe. Would that be why the cartoon left it off? Have you considered doing a new toy style head from scratch? I don't know a thing about customs and only slightly more about Shapeways but just wondering.
