A quick stand I whipped up for holding the mini temperature sensor and humidity sensor.

These can commonly be found online very cheaply (<$3 each). Often listed as:

Mini Hygrometer Thermometer Fahrenheit or Celsius Meter Digital LCD Monitor Indoor Room Round Humidity Temperature Gauge

They are the pefect thing for dropping in your drybox to keep an eye on your filament humidity. 

It stands on it's own, or you can use glue or some 3mm (1/8") screws to keep them in place.

This little holder is a tight snap fit with PLA and it orients correctly. Note the tolerance to the little tabs on the bracket is quite close. So check your settings, you may need to scale the model up 0.5% if you have trouble fitting, or if you use another filament that shrinks more like ABS.

Make sure you print with the model on it's face so the hole surface is flat on the bed.

After printing you should measure the following.

Hole diameter: 41mm

Width between slots: 42mm

The model shown was printed with bambu lab PLA metal.
