About the model
A desktop model of Concept 1 at 1:32: the same dome, legs on a common frame, a central rotating plate and a scissor ladder. Seven SG90 servos and an ESP32 controller with a Wi-Fi access point and a browser-based remote; all parts fit a 220 × 220 mm print bed. The model has been designed and calculated and the firmware compiles; a physical prototype has not been assembled yet.
