A basic desk mount for the Tasogen thermometer/hygrometer, which can be found here: https://a.co/d/5GPzgbE.
Laying these devices flat blocks the sensor ports on the back of the device, so I whipped up a simple stand that props it up for easy readability and sensor clearance. The hygrometer snaps in and has tight retention. Dimensions while standing with the hygrometer installed are approximately 28mm deep x 48mm wide x 42mm tall. It fits perfectly in the front of the Bambu AMS between the feeders, allowing you to monitor temperature and humidity inside the AMS.
I have only tested this with the specific device listed above, but it may work with other low-cost devices as well.
