Watermeter Sensus 620 prox holder

This is a holder for a M12 proximity switch to mount it on a Sensus 620 watermeter.
I use this to detect a pulse for every 1 liter of water passing through the meter, and log the water consumption in a home automation server (Home Assistant).

I printed it in PLA on an Ender 5. Layer height 0.12mm, 10% infill.
The M12 hole is intentionally thin-walled so I could force the proximity switch in if the hole was too small, but it ended up fitting perfectly.

I included the Fusion 360 file if you want to edit it.

PS: I manage in Fusion 360, but I'm certainly not very good at it. This is my first design uploaded.
