Mr. Chicken's Raven Kit neck joint upgrade

thingiverse

These parts are an upgrade for Mr. Chicken's Animatronic Raven Kit. These adaptors allow the universal joint included in the kit to be rigid mounted to the acrylic body panels with a keyed fit. I used an M3 screw to secure the adaptor to the acrylic panels. This requires drilling a hole through the acrylic to allow the screw to pass through the acrylic panel. The screw is secured on the opposite side with a nut. The universal joint slips into the adaptors and is secured in place with M3 screws which pass through the wall of the adaptor and screw into the existing grub screw threads on the universal joint. The head side of the adaptor has control horns for connecting a ball head end, allowing for a more secure linkage between the head and the servos, with less backlash. This allows for smoother, more controlled animation. Includes STL files for direct slicing, as well as a STEP file if you want to remix in your CAD software. These parts have a small contact area with the print bed, so small so I recommend printing them with a brim (I used 5mm). I used 100% infill with 3 perimeters, 0.1mm layer height. Print with the notched end of the adaptors facing upwards. The animatronic raven kit can be purchased from [Mr Chicken's Prop Shop](https://www.chickenprops.com/p/raven.html).
