This are the Attack on Titan (SNK) three-dimensional movement gear (3DMG) I made for my Eren Yeager cosplay n__n
Blade handles: They are made from 3 pieces of wood glued together and sanded. The levers are from bike brake handles, and the bracket holding them is a piece of cut and bent steel screwed in. The grip is painted polymer clay glued on. The tube is brake cable. The bottom has a coaxial connection screwed in so it can attach to the hip shooters.
Blades: They are made from wood. The black base is a piece of Sintra glued on. Blades can be put in and taken out of handles.
Blade Sheaths: The interior of the boxes is cardboard and it is overlaid with PVC foam (Sintra). All detail parts are glued on Sintra. Extra blades are wood. Gas tanks are cardboard poster tubes attached to the top of a water bottle and topped with plumping PVC. Wires are USB cables with a coaxial end attached at the end (so they can be attached to engine).
Engine: Most of it is constructed from PVC foam (Sintra) parts glued and screwed together. The hip shooters are EVA foam overlaid with Sintra. The black portion is a single strand of paracord wrapped around and fed through the hip shooters (to look like the harpoon cable). They can be connected to blade handles via a USB cable with coaxial ends attached. The top of the engine is EVA foam. The engine unit is attached to a heavy-duty nylon belt. The fans are painted 120mm pc fans. They are wired down through a PVC pipe and into the central box onto a switch a 12V RC battery. Fans can run for several hours uninterrupted (good for fighting Titans :p)
Hope you enjoy! If you have any questions about the build process or anything else just shoot me a message :)
I will likely post more detailed construction pics/descriptions of this stuff in the future ^_^
The absolute BEST Mad Max cosplay (we did get a pic of an awesome Furiosa later). Since it was all mobility vehicle it was very slow, which meant ihad the BEST grand entrance wherever it went, like a parade float. I talked to the guy I a little, he was super nice and cool and he was having a lot of fun. SUPER CLEVER costume idea.
