The prompt
Create a parametric 3D-printable rigid mounting plate for an ADXL345 vibration sensor. Sensor PCB: 20 mm × 16 mm. It has exactly 2 mounting holes, diameter 3.2 mm, with 15 mm center-to-center spacing. Make the plate 35 mm × 30 mm × 4 mm. Create two sensor mounting holes with 3.4 mm diameter and exactly 15 mm center spacing. Center the sensor on the plate with equal edge clearance. The ADXL345 has soldered header pins on one edge. Keep that edge completely unobstructed and provide a small cable-exit/strain-relief feature on that side for a flexible 1 m SPI cable. The sensor must sit directly and rigidly on the plate. No rubber, foam, springs, flexible arms, or vibration isolation. Add engraved X, Y, Z orientation markings. Use 0.3 mm general FDM clearance, rounded edges, and geometry suitable for PLA/PETG printing. Keep all dimensions parametric/editable. Generate a solid mechanical CAD model suitable for STEP/STL export.
