There doesn't seem to be much available for the Proxmark3x, so this case is remixed from a nice, well-made case that Concorde edited to fit the Proxmark3_Easy.

His case design had a thinner floor and ceiling to better improve antennae transmission.

I took his design, removed the spacer to allow USB-C Access, added spaces for the PM3X Switches, added labels for the switches, and holes for the status lights, Labeled the Antennae and added holes for the Read and Write buttons.

Hope others find this useful.

Edit: Altered the text on the top case to be deeper and wider to print better.

Edit: Added a Topcase for use with the LF Circular Antenna V1 made by XEMON on DangerousThings.com

Use Tree Supports, enable thin walls to get the text to show up better. Best to print in the orientation shown in the All Files.
