This badge depicts the emblem of the Adeptus Mechanicus from Warhmmer 40K, which also comes with its own mechanical presentation box. You will, of course, need to source the pins and caps to hold it on!
If you don't have a 3D Printer and you want one of these produced, please send me a DM and we can arrange for me to print one for you :)
