How to cover my devices?

I bought some devices from Sparkfun, and they work well.

The main devices are:

SparkFun RedBoard Qwiic

SparkFun High Precision Temperature Sensor - TMP117 (Qwiic)

Later I added an LCD display 16x2

and a

4-digit 7-segment display modul TM1637

from other online store.

The LCD is attached and works. Maybe later I intend to add or replace it with the 4-digit 7-segment display.

I intend to add a battery holder too to secure power to this device.

Question:

How can I cover all these devices under 1 piece of cover?

This is a temperature measuring device and I wish to use it inside a house like any other handheld devices.

I hope you have suggestions for this.

Housing, enclosure, case.
