This part fits on water meters with two screw pillars on the glass. One side has a slotted hole so the offset of the induction sensor to the pointer can be adjusted.
For my water meter (Kiwa sensus) the center to center distance of the screw pillars is 34,9mm and the diameter 5mm.
If you have different dimensions I included the Fusion 360 files so you can adjust it to your needs.
Print it with supports on the build surface.
