the desplay and probe i got off ebay for like $12 and it is meant to be for a water cooling set up in a computer but i just have the probe hanging in mid air so it takes a measurement of the ambient temperature inside the printer.

i used fusion360 to design a mount for the probe and the mount for the display it self.

if you look up digital temperature gauge on ebay you will finde it
How did you wire up its power supply?
