Shell for NRF24 shield for the T-Lora Pager

The Lilygo nRF24L01-PA Shield comes without a case, leaving it open to the elements.  I wanted to create a shell for the board so that when I carry it connected to my T-Lora Pager, it will be a little more protected. 

This case is "snap together', so it does not need screws or adhesives, and it is snug enough to prevent the board from rattling around inside the case despite the fact that is uses the case itself to secure it.  Getting the tolerances right took a fair amount of trial and error.  The top slides on over the board and friction holds everything in place.  By forgoing screws, I have made the case very thin and light,  which I felt was a good trade-off. 
 

NOTE: When sliding the top onto the case to secure the board, please be careful to make sure the board is seated correctly.  In order to stop the top from falling off, I made it fit tightly, so it requires a little presure to seat the top.  If you aren't careful, the top could knock one of the semiconductors on the board as you are closing it. Apply pressure, but dont force it so hard you dont control the closure.   I'm not responsible if you damage your board assembling it.
