This is a housing for a humidity/temperature sensor, to be attached to a 2020 aluminium extrusion. The photo shows it mounted to the 2020 extrusion of a BIQU B1.
This is compatible with standard size humidity/temperature sensors, in my case I used "Mini Digital LCD Indoor Convenient Temperature Sensor Humidity Meter Thermometer Hygrometer Gauge".
Fusion 360 archive included to allow further tinkering.

Notes:
You probably want the print facing downwards, so that the part that slides into the aluminium extrusion faces upwards. I used standard Cura supports.
