Fits these cheap temp sensors that are commonly found like: https://shop.alphacool.com/en/shop/controllers-and-sensors/temperature-sensor/17573-alphacool-core-temperature-sensor-with-c/f-display (reference since I have no idea where mine comes from!)

The bracket is aimed to fit with a standard PC case screw into whatever you can find (i'm using my radiator).

Printed in PETG with 30% infill wih no supports.
