KIRA is a complete 3D-printable desktop robot — not a static figurine, but a full mechanical build: an expressive head on a pan-tilt neck, seated on a geared base that rotates the head. Designed from the ground up for clean FDM printing in PETG, with every hole sized for real M2–M5 hardware, heat-set inserts and press-fits — so the parts go together without scaling or filing.Print it as a display piece, or bring it to life with electronics. The reference build runs on an ESP32-P4 with a 4.3" display driving the face, plus servos for the neck and geared drive, LED light-guides and a speaker — and the mounts are adaptable to other controllers.Highlights:
