hey @Concorde i really like your case and it seems to be the only one to fit the Proxmark 3X. i was curious if you would be willing to further modify it for me.
The 3x has a battery and a switch to activate the battery, as well as Read and Write buttons. Also the separator you have for the button on the left needs removed to access the USB-C connection.
I mocked up a quick diagram using your case, shaded areas would be spots for the proposed cutouts.
