I built this Bender from Futurama costume from scratch, mostly stuff from a surplus supply store, Lowes and Hobby Lobby. It took me 2 weeks to complete working on it every day after work. I actually see through the teeth area, and the top of the antenna is 7’10” tall.
There is a battery operated fan mounted inside the top of the head to keep it cool inside, and the door on front opens to reveal a beer holder inside. For those of you that have seen the show Futurama you will know that Bender loves his beer.
