Thermometer Holster

I have an indoor/outdoor thermometer to keep track of how hot the back of my Expedition gets. I drive pretty regularly with two dogs in the back, and over the summer and winter the temps can get a little extreme.

I need to be able to take it out to keep an eye on it remotely (it has about 1/4 mile range) but also have it not rolling around while I drive.

There was a coin holder there that I popped out, and used as a template for an insert to keep this mounted semi-permanently.

Printed with kinda crappy Amazon Basics PETG. If it holds up well, I'll reprint it with better quality black PETG so it matches the car better.
