drilling machine 3d model

Create a detailed CAD-style 3D model of an automated coconut drilling machine. The system has a 400x300mm base with two vertical side frames supporting a horizontal shaft. The shaft is driven by a NEMA 23 stepper motor (via coupling) and rotates only 180 degrees. At the center is a hub with an eccentric cam that pushes a vertical sliding rod downward using a follower. The rod holds a V-shaped coconut clamp (140mm). At 180°, the coconut moves down onto a fixed vertical drill (500W, 43mm mount) aligned with the shaft axis. Include a water nozzle near the drill for cleaning and a drainage tray below. Add a straw guide tube near the drill hole. Show ESP32, TB6600 driver, 24V SMPS, relay, and neat wiring paths. Include limit switches at 0° and 180°. Industrial, realistic, precise alignment.
