This is an adaptation of the Piranha Games Battletech mech game Shadowhawk battlemech. It is the hero version, the "GrayDeath": The original mesh was supplied by Minimalistix here on thingiverse. The hands are customized to four finger human hands instead of the pinkie thumb of the original.
There are no internal polys to cause unnecessary printing, so the lines should come out cleaner. Technically the arms and legs are separate mesh's, however they are arranged in the combined state if you want to print it all up.
