These hygrometer/thermometers are super cheap on Amazon. I wanted to be able to view one on the outside windowsill from inside the house, but I couldn't get the angle the way I wanted. I designed this to solve that problem.
It's ventilated to ensure an accurate reading, and holds the LCD at a 45 degree angle.
If your printer has decent part cooling and can bridge well, you won't need supports. If it doesn't, the support should be minimal with only a single support line under the top of the main opening. Hint: set your "Support Overhang Angle" to over 45 degrees. You may need to use support blockers for the side openings, but they should print well with a low layer height. I used 0.16mm for mine and they came out great with no supports at all.
These are the ones I bought. Many vendors sell them. They also come in centigrade/Celsius for those of you not using barbarian units. :^) https://www.amazon.com/gp/product/B08PVLF8LD
