Designed and built it from scratch. Two cameras in front to provide stereo vision, screens inside for each eye, built-in ventilation fans with moving shutters, red backlight along the seams, and a small screen that shows fans mode. Some switches and rotary knob to control it. Arduino running the whole thing.
The main structure is printed from CF-polycarbonate, and all the small detailed parts are SLA— red transparent for glowing bits, simple white for everything else. Painted the whole thing straight from a spray can. Shell panels are removable and held in place by magnets, stays on and don’t rattle even if you shake your head violently.
There are 177 printed parts total (not counting screws, mosfets, leds, magnets, wiring, etc.). Powered by any USB-C power source, lasts for a 3-4 hours.
Whole thing designed in SolidWorks.
