Inspired heavily by Bluetopia's shaker motor case, but designed to accommodate a larger shaker motor, specifically this one:
BestTong DC 12V-24V 8000RPM 775 Brushed Vibration Motor DOUBLE-HEAD High Torque Electric Vibrating Motors with 2 Iron Rotating Mass https://www.amazon.com/gp/product/B07VFX8N1J
You'll need M5x40mm screws or similar to secure this to your pincab. Remember to install a flyback diode on this type of feedback device!
