As the title says, it's a basic support for a InkBird ITH-10 thermometer. You can put it in your enclosure while printing so you can monitor the inner temperature of it. You can also use it as a stand so you can put your thermometer wherever you need it.
Nothing special here. You can print it as is, you can print it on its side... No need for support material.
