I have installed an NRF24 module in my Lilygo T-Embed, so I created a back cover to accommodate two external antennas for 2.4GHz and 433MHz. Also it can be used if you like to install two external antennas to improve signal coverage.
It consists of a back cover to which you will need to add the SMA-IPX connectors and 4 magnets of 8x2mm, although it is also possible to secure it with screws.
For printing, the best way is with the internal cover facing down. Once of the SMA connectors are placed, they can be covered with the covers using a bit of adhesive. I recommend using PETG or a similar material and a 100% infill to make the support for the connectors and the assembly as rigid as possible.
In addition, I have created a 6x4mm housing for a micro push button that I have soldered in parallel with the BAT of the board to avoid opening the device too often.
If you need a guide for the installation process of the module, you can find all the information here:
