The video on the right here shows an Endo-01 head from FNAF 1. This is still a work in progress especially for the neck mechanism, other than that the head works just fine. It has connections for the eyes to be placed onto it, there is also spaces at both sides of the top of the head open for ears to be placed, depending on which animatronic is going to be used. The jaw does open and close, with magnets underneath. The original idea for that was the magnets could connect to the animatronic outer head, as the Endo head was speaking the outer jaw would move also. However, we might have to change the magnets to screws, as the magnets might not be strong enough to hold the outer jaw in place. In the mouth there is a speaker hole for the animatronic voice to be heard from (we will be making an animatronic voice box later on).
Endo-01 head
Freddy Fazbear head
Here you see on the left is a Freddy head. This was originally for the Endo-01 head to be used an actual animatronic. The head ended up being a failure, but a good failure. As this allowed me to realise my mistakes and to re-design it so that it can work. So, instead of leaving this in the bin or in a spare parts box, i decided to make it look old and abandoned, by using a soldering iron to go around the head making it look corroding, as if it was abandoned in an empty Freddy Fazbears establishment for decades. The main problems with it was that it is the wrong size, the Endo head could not fit with the jaw attached, and much more. We will go back to this project in the future when we have time.
Unfortunately this versions doesn't allow you to wear the Freddy head. However, in the future we will change that so you can wear it and cosplay as Freddy or have it up on display, so the 3D file might go up for sale later on.
