DRESS LIKE IT'S 2099-Disclaimer: this tech might make you feel like you're straight out of some sci-fi franchise-looks cool regardless of material color or material type used to print it-requires a couple of MG90S servomotors to operate as intended-front shell (the opening part on the jawpiece) requires the use of 4 small magnets 10x3mm to attach and detach seamlessly-a microcontroller (arduino and similar type boards will do the job as long as you can load a simple servo sweep/knob code with your preferred interface ex. potpin or pushbutton) is necessary-a battery that can support the entire circuit load (5-7.2V 450-500mAh li-ion or nickel cadmium) with a buck coverter (booster or stepdown depending on your configuration)-a bunch of 3 & 4 mm wide bolts or scfews-some cables-use tree supports with medium-high overhang angle-best results range from 0.14 to 0.26mm resolution-use vynil or hot glue to secure the magnets as shown in the 4th picture-use of glue for cheek-to-chassis apparatus is recommended-check images on product showcase for instructions and details
