This is a case for the Qwiic Ultrasound Sensor https://www.sparkfun.com/products/17777 that can be mounted from behind. It also works with the identical (apart from colour) Zio Ultrasound Distance Detector https://www.smart-prototyping.com/Zio-Ultrasonic-Distance-Sensor.html.
Other designs for the original HC-SR04 board don't work for this since there's an odd design decision to mount the Qwiic connectors on the board's reverse. Considering this thing needs to point in the front direction, this is awkward as you cant easily mount it from behind with the connectors in the way.
This case is a very snug fit and the board stays pretty still in there without even being screwed in since the tight fit around the sensors ensures it. On the back are cable runs so you can have the Qwiic I2C cable coming out where you need it. You also have access to both Qwiic ports so you can unplug them without unscrewing the case.
It is composed of the case that holds the board and the backplate. The case and backplate are connected with screws. It is intended for use with 4x m3x5.7mm threaded inserts. I used these https://www.3djake.uk/3djake/threaded-inserts-50-piece-set combined with 4x M3x6mm Phillips pan head machine screws.
In my application, I use double-sided sticky tape to mount it, but you could probably get longer screws and mount it using the backplate screw holes to anything you want that way as well.
