I started with [thingiverse/thing:3738687 by SantiMZ], and added an assembly for the ESP32 and the associated electronics. All parts are inserted in a standard PVC pipe which is fixed on top of a water tank. A mobile cover protects the assembly.
I wanted to be able to tune the horizontal plan of the ultrasonic sensor, from the top; this explains the ‘tricky’ vertical supports. During the design of these, I used the ‘mirror’ copy feature with Blender which ends with turn left screws; those are indicates in red colors.
All parts are printed in PETG with 0.2mm layers. "Vertical supports" are printed with bed support.
