Paper Mech Rack & Pinion (Laser cut)
The singing mechanism is based on the PaperMech rack and pinion. The lower gear is removable and allows for the option of controlling the mechanism by hand (by turning the lollipop stick), or using the servo.
The body was painted with watercolors and glued to the rack and pinion frame. The mouth is formed by a strip of cardstock glued into an oval. A small piece of a BBQ skewer is attached to the rack as a "pin" that inserts into the mouth to open and close it.
