This badge depicts the 'Wrath of Khan'-era Starfleet Insignia badge, worn on the left-breast of the uniform jacket. The badge comes with its own 'Search for Spock' tribute photon-torpedo tube presentation box. You will, of course, need to source the pins and caps to hold it on!
(NOTE: if you're printing the box itself you'll need to stop the print at approximately 60% then change the filament from black to red)
If you don't have a 3D printer but you'd really like one of these please send me a DM and we can arrange for me to produce one for you, or check out my Numonday store:
