Printed mounts for HC-SR04 type ultrasonic sencor mounts.
I have tested these, printing in PLA, and they have gone together with no problems. some minor post-processing may be required (run the blade of some scissors around the inside of the large holes) to get sufficient clearnace for the ultrasonic sensors.
I went through a few iterations of the design to get a well fitting design with clips that work effectively.
The two designs that I have uploaded allow it to be bolted to a vertical or horizontal surface.
There is space allowed in the design for your cables to connect to the 4 pin connection.
Note: I've included the solidworks file, as well as a solidworks assembly file, as I accidently aligned the part file incorrectly. if yo modify the Part file, you should export the STL from the Assembly file, to get it correctly aligned.
