As there was no case for the Manta M4P, I designed my own version. With this setup, the EXP connectors are inoperative, I can change the box if someone wants to use them, it's a matter of changing the cable entry and increasing between 6 to 9 mm in height and that's enough space. I didn't mention it in the video but the first GPIO pins are also inaccessible but it's something I can also change if someone needs it.

You can check the assembly here:

Have a nice day ;)
