Sonar bracket for 210mm drone frame (HC-SR04)

This is a simple mount for the HC-SR04 sonar sensor for my 210mm drone. The bracket interlocks with the bottom plate and the rear stands. Stands are 5mm wide with a 25mm space between, bottom plate is 3mm. The drone is a basic 210mm frame.
Sonar can be used in Betaflight/Cleanflight to hold altitude, which is ofcourse not really needed on a 210mm racing drone, but I like to experiment with the frame.
